What to Do When You Have Hot Water but No Central Heating?

Gone are the days of shivering and suffering in the cold, central heating system is a revolutionary method to provide a cosy and relaxing environment in the house. Central heating has become an essential part of every house in the UK. You can relax in a pleasing and comfortable environment after a long, exhausting day at work.

Since their invention, central heating systems have evolved extensively and have become more energy efficient than ever. There also are some choices available that you can choose from, i.e.:

  • Furnace-based systems heat the air and then distribute it in the house
  • Boiler Based Systems heat the water and circulate it around the system to provide heat.
  • Heat Pumps systems extract hot air from the outside and then distribute it in the house.
  • Hybrid Systems combine furnace and heat pump systems to provide more efficiency.

However, heating systems, due to their complexity or negligence in maintenance, can suffer problems which result in total or partial loss of heat in the building. Some of these problems can be minor and can be fixed with a little effort. While some problems may require more professional hands to perform repairs efficiently.

In this blog, we have explained some of the common problems that can cause the loss of heat in the house.

Check if the Radiators are Warm or Not

Check Your Settings

Make sure that all the settings are correct and that the system is on. In case of a power cut, your boiler may have reset, and you will have to apply your settings again. Check the thermostat settings and make sure that the timers are correct. You can move to the next step if you don’t find any problem in the settings.

Check if the Radiators are Warm or Not

If you are getting hot water but not heating, you may need to check if your radiator is working or not. If it feels mildly warm, you may be able to fix the problem by bleeding your radiator. On the other hand, if your radiator feels warm at the top and cold at the bottom, you may need to power flush it to fix the problem.

How to Bleed Your Radiator?

Bleeding your radiator is a simple procedure. You need to locate the bleed valve and open it with a radiator bleed key by turning it anti-clockwise. This will eradicate any vacuum that was causing the loss of water supply in the radiator.

How to Power-Flush Your Radiator?

It is better if you hire a professional for this one. He will attach a piece of specialised equipment to your heating system and pump water at high pressure into it. It will clean the radiators and ducts of any debris and sludge that has accumulated in the system.

Check the Boiler Pressure:

Check the Boiler Pressure:

Central heating does not work properly if the boiler has lost water pressure. Check your boiler to see if the pressure is right or not. If you see low water pressure in your boiler, you may need to repressurise your boiler by referring to the user manual.

Sometimes, there is a reset button given outside the appliance surface. If that is the case for you, you can try and reset your boiler as well. Moreover, you can cut the power supply, wait for 30 seconds and turn it on again. This will also reset the boiler settings.

Problems with the Diverter Valves:

Diverter valves are used to switch heat between central heating and water supply. With the passage of time, they can suffer some issues, and these valves can stop changing their position; resulting in the loss of either the hot water supply or the central heating.

However, make sure that all kinds of repairs are made by a professional to attain maximum safety.

What if the Problem Sustains?

There is almost nothing that you can do yourself. If the problem is not fixed, then we recommend engaging a certified professional to carry out some diagnostic checks and locate the problem.
