Combi boiler - A combination (or combi) boiler is the most commonly available in the UK. Its small and simple design takes up minimal space, whilst supplying hot water directly to your taps or radiators without the need for a bulky storage tank. It provides hot water on demand meaning you pay only for what you use. The main advantages of a combi boiler are energy-efficiency, and affordable installation process.

Conventional boiler - A conventional boiler is also known as a regular or heat only boiler. They are normally found in older homes, however, they can still be convenient for modern buildings, depending on the demand for hot water in that home. Conventional boilers heat your home through a separate water cylinder that is usually found in the loft. They are a great option if your area has an issue with low water pressure.

System boiler - A system boiler obtains water directly from the mains. It uses a large tank of stored heated water, so it’s possible to use multiple taps at the same time without that dreaded reduction in pressure. This is ideal if your home has more than one bathroom or multiple people using water at the same time. Although it uses less space than a conventional boiler system, it’s more complicated and needs more space than a combi. System boilers also need to be well insulated to make sure that the water remains heated within it.

If boilers are left inactive for a period of time (like during the summer), there is a higher probability of seizing up. Regularly turning on the heating is an excellent way to prevent this from happening. This is especially important during the winter when temperatures can reach below zero, causing the pipes surrounding the boiler to freeze up if it isn’t turned on. If this happens, it can cause the boiler to cut out and require repair – a cost that could have been avoided. We recommend having your boiler serviced once a year and most manufacture warranties stipulate this. Otherwise, the Boiler warranty will not be valid.

Usually installing a boiler will take around one day to complete; however, this can change be depending on the system in place or weather any repairs need to be carried out. Our team will always confirm how long you can expect the installation to take before starting the work.

A Gas Safety check is to ensure that your appliances, boiler, and installation are safe and working correctly. A service includes performance tests, specific instructions by the manufacturer and necessary remedial works both are required to keep your gas fittings in full working order.

Yes, legally it is your responsibility to provide your tenants with all documentation relating to the gas safety check of the property they are occupying.

If your radiators aren't heating up properly or they have cold spots, you might need to bleed them. Radiators need bleeding when they have air trapped inside them. This trapped air stops warm water circulating around your radiator. That can make the radiator cold at the top, but warm at the bottom. It means your central heating system isn’t working efficiently and it can take longer to warm up your room. It can also cost you money, as your bills will be higher. You might also need to let out trapped air if you have noisy radiators which are making banging, clanking or gurgling noises.

Follow our steps below:

- Turn off your heating
- Use your radiator key to turn the valve at the top of the radiator
- Retighten the valve once the hissing stops and only liquid comes out
- Turn your central heating system back on
- Check the pressure by looking at the gauge on your boiler

It’s recommended that you bleed your radiators once a year, even if they are working properly.

However, if the radiators are still not heating up this could also be an indication that the central heating system has sludge present in it. This causes your radiators to not heat up properly and/or experience cold spots (e.g. they are often cold at the top and warm at the bottom). A good old power flush service is usually the best way to resolve this.
