How does a hot water boiler work?

Hot Water Boiler Repair

Components of a typical hot water boiler.

The hot water system includes a boiler for heating (butNotboil) water, a network of pipes that distribute the water, and radiators that heat different rooms. Hot water heating systems use the same type of boiler as the onesteam heating systemuse. Controls include a combination gauge (or altimeter) that allows you to check water temperature and pressure and alerts you when the boiler needs water or is malfunctioning. In some systems, the pressure relief valve automatically manages the water. The typical system also has an expansion tank which must be properly filled with air to prevent the water from boiling. Newer systems often place the expansion tank in the basement ceiling near the boiler; they also include a purge valve to evacuate water and let in air as needed. Older systems sometimes have the expansion tank in the attic and include a gauge similar to that of the boiler.

What can go wrong with a hot water boiler?

Because they have few mechanical parts, hot water systems often operate reliably for many years. The most common problems are with the expansion tank or circulator rather than the boiler. Here are some symptoms of the problem: The hot water system may not produce heat or heat poorly, and a leak may occur. Some heaters may not heat up while others do. Pipes may tinkle.

Troubleshooting tips
Place a pan of water on the radiator to add moisture to the air during the winter, if needed.

How to identify hot water boiler problems?

  • If the appliance does not generate heat, turn up the thermostat, check
  • change
  • ,
  • fuse
  • ,
  • circuit breaker
  • , and the water level. Also check burner safety controls (see below).
  • If the unit is not generating enough heat, check the combination meter, then the expansion tank (see below). Then drain the boiler (see below). If water is leaking from the pipes of the heating system, try to fix it yourself.
  • If only some of the radiators in the system heat up, air is released from the coolers (see below). If you think the circulator needs repair, call an experienced technician.
  • If the pipes suddenly start ringing, the circulation unit may need professional service or replacement.
  • If there is a chronic knocking noise, check the slope of all return lines; they have to bow
  • towards
  • The boiler is working properly.
  • If a radiator is only slightly but evenly warm, water can be trapped inside. Make sure the radiator is tilted back; if not, insert a wooden spacer on the rear-facing bottom.

Troubleshooting tips
The water pressure in the water heater is maintained automatically by the pressure relief valve. Periodically check the combination meter and call an experienced technician if the valve needs to be repaired or replaced. If your system does not have a pressure relief valve, you can manually feed water to the boiler by opening the feed water valve and closing it when the pressure reaches 12 pounds per square inch. High water consumption is caused by leaks in the supply or return lines or in the boiler itself.

What do I need to repair a hot water boiler?

Most hot water boiler system components are available from major plumbing suppliers. Check your local phone book. For basic inspection and repair, you will need the following tools:

  • Screwdriver
  • pipe wrench

Troubleshooting tips
Here’s how to read a combined unit of measure. The moving cursor indicates the actual pressure. The fixed pointer indicates the minimum pressure. If the moving needle drops below the minimum, the system needs water. The lower thermometer indicates the water temperature. The maximum boiler water temperature is set by moving a pointer along the aquarium slide. Do not attempt to adjust the aquastat.

What are the steps for repairing a hot water boiler?

Troubleshooting the hot water boiler expansion tank:

  1. Check pressure relief valve. If water overflows from it, there is too much water and not enough air in the tank.
  2. Touch the tank wall; The lower half will be warmer than the upper half. If the top is almost as hot or as hot as the bottom, the tank is full of water and needs to be drained. Once the system has cooled, attach a hose to the tank drain valve and drain 5 to 10 gallons of water from the system.
  3. Return all valves to normal settings and start the boiler. Check the system pressure on the combined pressure gauge. If out of range, call for service.

Drain rusty water in the water heater:

  1. Turn off the power and open the drain valve and vent to the highest radiation units.
  2. If the boiler has a manual feed, open it.
  3. Once the water is clear, close the outlet and vent and wait for the pressure to reach 20 pounds per square inch (psi) of pressure.
  4. Melt each radiator until the pressure reaches 20 psi, then drain all the water. If pressure drops below 12 psi, add more water.

Melting the hot water boiler radiator:

  1. Open the vent with a screwdriver or special tool that came with the heater.
  2. When water (instead of air) comes out, close the vent.

Popular questions about how to fix a boiler heater

How do you fix a boiler that is not heating?

How to fix a boiler thermostat not working
  1. Replace the batteries in your thermostat.
  2. Clear any settings and restore to manual operation.
  3. If all else fails, refer to the thermostat manual.

Why is my boiler on but no heating?

If your boiler works but the radiators are not heating up, then likely cause could be a faulty boiler pump or your central heating controls. If your boiler works but the radiators are cold, check that the thermostat or timer is working correctly.

How do I reset my boiler heater?

Follow these simple instructions to reset your boiler:
  1. Refer to your boiler manual.
  2. Push the reset button for 10 seconds.
  3. Wait 2 – 3 minutes, the boiler should fire up.
  4. Repeat twice if the first attempt fails.
  5. If the boiler still fails to fire up on the third attempt, double check the gas supply.

How do I get my boiler to work again?

Push the reset button for 10 seconds

Generally, you push the reset button and hold it down for 10 seconds. Do this only once. Wait for 2-3 minutes, as the boiler may be starting up. If the reset has been successful, then the flame will ignite in the boiler.

Why has my heating stopped working?

Dirty and clogged filters are one of the primary causes of furnace problems and can cause high operating costs. The heat exchanger can overheat and shut off quickly when filters are clogged with dust and dirt. This also causes soot buildup on the heat exchanger, which makes your furnace run less efficiently.

What do I do if my heat isn’t working?

Why are my radiators cold when the heating is on?

Why is one radiator cold when the heating is on? One cold radiator usually indicates that either there is air in the system or there is a stuck valve within that radiator. The thermostatic radiator valve (TRV), like the one pictured below, controls the flow of hot water to the radiator.

Why have I got no hot water or heating?

No heating or hot water

This issue can be caused by anything from faulty motorised valves, broken system diaphragms and airlocks, to low pressure or a broken thermostat. To determine whether this issue is caused by low pressure, you should check your pressure gauge to see if it is below 1.

Why are radiators not heating up?

Check for Trapped Air and Bleed Your Radiators

If just one (or a few) of your radiators aren’t heating up, the most common reason for this is trapped air. If you’ve just turned the heating back on after the summer, air can become trapped in your radiators, causing them to be warm at the bottom but cold at the top.

Where is the reset button on a boiler?

Your boiler restart button, also referred to as ‘lock out’, is located on your boiler burner unit. Usually, the burner unit front door cover will need to be removed to gain access to the control box reset (when ‘tripped’ the button is normally illuminated).

Do all boilers have a reset button?

All boilers have a reset button but its location and how to use it varies from model to model. If you can’t see the button, then check the manual that came with your boiler. This should also explain how to reset your boiler.

What does blue light on boiler mean?

The blue light on an RI will flash when it detects no gas supply, or low pressure. This could be a range of things such as a faulty gas valve. As this issue relates to gas, contact a heating engineer straight away. Another common cause of a blue light flashing is a blockage in the flue.

Can a boiler explode?

While historically, boilers would over-pressurise and explode with alarming regularity, modern boilers are manufactured to be able to withstand excessive pressure, and can typically handle an operating pressure of 20 PSI. When pressures increase beyond this level, the boiler can fail, which can lead to an explosion.

Why does my boiler fire up then cut out?

Your combi boiler firing up then cutting out is nothing to worry about. It is usually the result of its ‘preheat’ function. Basically, it’s a way of ensuring that hot water is ready to be used in the taps throughout your home.

Is broken boiler an emergency?

If your boiler has broken, you should contact the manufacturer first and they should send a service engineer to your home.

HOW TO FIX YOUR COMBI BOILER. Topping up the pressure, Check that you have gas, Power to the boiler, Controls are turned on. My name’s Allen Hart, and today I’m going to show you some basic things to check before you call out a gas engineer or plumber if your boiler’s not working. So, I’ve got a few different boilers, I’ve got an Ideal Logic here, and I’ve got a few other boilers in the other room. I’m going to go through some different faults, and also, when customers phone you up, some of the common things that are faulty, and don’t need a gas engineer to go out. So, just DIY tips that you can do yourself should you have a problem. Let’s have a look now.

I’m going to show you on a few different types of boiler, so we’ve got a Glow-worm here. If you find that your display is blank on the front of the boiler then just go and have a look at your spur and make sure the electrical isolation is turned on. So, a very common fault is that that gets knocked off with towels in the airing cupboard, or if it’s in the kitchen, kettles, and microwaves, and stuff just knocking onto it, so just check that you’ve got your power on to the boiler.

So, you’ve checked that you’ve got the power, then you need to check that your controls are calling for heat. So, try and find your timer. There are all different types of timers, but try and find your timer and then make sure that’s turned on. And then, next thing to do is go and find your room stat, so if you’ve got a room thermostat, so we’ll go and have a look at that now, see if we can find one.

We’ve found the thermostat, on this one the thermostat is turned down. If we turn the thermostat up then hopefully that would fire the boiler up, so you just need to check that that is turned higher than the temperature of the room for it to come on. Obviously the higher it is the warmer the room should get. So, let’s have a look at some other common issues now.

You can also check that you’ve got gas. It may be that you’ve got a gas tap in an under stair’s cupboard, or something like that, and it might’ve been knocked off with a box, you might have put something away. Or, it may be that you’ve got a gas token meter, and you just need to get some credit for it. So go to your credit up, reestablish that, and then hopefully that might help you as well. We’ll go and have a look back under the boiler now. We’ve got another few tips that might help you as well, so let’s go and have a look at them now.

Another thing to check is the pressure gauge on the front of the boiler. It may be that your pressure gauge is low like this one is, and then that might just need topping up. I have done quite a few videos on how to top up central heating combi boilers so you can check out one of them. I’ll add one in the link below, but I’ll go through that now as well.

If you did find that your pressure was low then it may be that you need to top up the pressure so you may need to find a filling loop like this one. There are all different types, sometimes they’re built into the boiler as well, so on an Ideal Logic, they’re built into the boiler, there. And then, on this one that’s just a flexible connector.

So, if you want to fill this system up all you do is open the taps, open this one and open this one, do that very slowly. Then you can look at your pressure gauge on the front of the boiler, and then you’d get that back up to about one bar, making sure that you don’t put too much pressure in. So, I’ll show you the front of that now with the pressure on. On this Vaillant, we’ve topped the pressure up, and then if we have a look at the front gauge we can see now that the pressure is back up.

So, hopefully, you’ve got your boiler back up and running now. Please remember if you’re going to work on a gas boiler, if you’re going to take the combustion case off you must be Gas Safe Registered. I would never endorse anybody working on gas unless you’re safe to do so and you’re competent to do so. I hope this video was of some use.
