Frequently Asked Questions

q: Which heating and hot water system is right for me?
  A: Whether you use gas or oil, choosing a new boiler is a big decision. The sections below show the main system types, how they work, their advantages and what kind of homes they work best in. If your new boiler is going to be fitted onto your existing heating system, we may need to review the state of your existing pipework and radiators as this could cause damage to your new boiler. No installation is the same and our professional heating engineers can provide you with expert advice and free quotes.
q: What is a Combi Boiler Heating System?
A: A combi (or combination) boiler is a high efficiency water heater and a central heating boiler in a single compact unit. Combi boilers heat water directly from the mains when you turn on a tap, so you won’t need a hot water storage cylinder or a cold water storage tank in the roof space.

This makes them very cost-effective and energy-efficient as water is heated instantly rather than being heated and then stored in a cylinder. An additional benefit is that your hot water is delivered at mains pressure, which means that you can get a powerful shower without the need for a separate pump.
q: Can I have a temperature control app on my mobile phone?
A: Smart, or intelligent, boiler controls can learn how long it takes to heat up and cool down your home, and monitor external temperatures. They’re great for energy efficiency.

They can also be controlled via an app on your smart device, these learn from your system’s behaviour, use live weather data, keep track of your fuel usage and more.
q: Is a cylinder necessary when fitting a new gas boiler?
A: Whenever a system or regular boiler is installed, there will always be a requirement for a hot water cylinder. Hot water is provided by taking heat from the boiler and pumping it through the central heating system to the cylinder where the heat is transferred via the cylinder’s heat exchange coils. This water is then stored ready to be passed through taps and showers when required. If you have an existing tank or cylinder, we will always accommodate this wherever possible to minimise costs. However depending on the age and condition, we will advise you as older, non-insulated cylinders tend to lose a considerable amount of heat and are likely to have a build-up of limescale, which reduces efficiency and makes water heat-up times longer.
