Apex Plumbing and Heating are independent Gas Safe Heating Engineers. We install boilers from all major manufacturers, but generally lean towards those offering better quality premium products.
Modern condensing boilers have varying levels of modulation – the higher, the better! Making full use of this feature enables greater efficiency with improved heating comfort. Smart controls using OpenTherm or other two-way communication protocols are essential. For this reason, the complete system package must be designed to allow seamless integration with advanced modulating boilers.
There are three main types of boilers – Combi, Regular and System, which are all condensing boilers. Their efficiency is measured on the ‘SEDBUK’ scale. SEDBUK stands for ‘Seasonal Efficiency of a Domestic Boiler in the UK’, with ‘A’ being the highest rating ( 90% efficiency or over).
Combination boilers provide both hot water and heating. Hot water is produced on demand, without the need for storage tanks. Simply opening a tap or ho water outlet will fire the boiler. Combi boilers are ideal for flats or smaller properties, where space is at a premium. However, the mains pressure and flow rate must be verified to ensure it is adequate. Time and temperature controls are required to program the heating system.
Regular boilers (also known as ‘conventional’ boilers) are used for central heating systems, and hot water via a storage cylinder. Typically, these are installed with vented heating systems, having a feed and expansion cistern in the loft. The heating components, such as pumps and motorised valves are required in addition to the actual boiler.
System boilers are similar to Regular boilers, but include many of the heating components already built-in to the boiler. This generally makes installation quicker and easier. System boilers are installed with a sealed heating system which therefore removes the need for a feed and expansion cistern.
