High-efficiency condensing "combi", or combination boilers, are very popular in homes today because they can save space and money. A combi boiler is a compact and efficient unit that provides all the heat and hot water for a large home, while saving on operating and installation costs. Combis work like both heating boilers and tankless hot water heaters and are so compact they can be hung from your wall.Why choose a Combi boiler?Here's some of the reasons why people are turning to Combi boilers:High Efficiency: All equipment we specify and install has a minimum efficiency of 94%.Cost: Combi Boilers are very efficient, allowing you to heat both your home and water quickly when you need it. This reduces the need to use the boiler when it is not required. There is also no need to heat up a separate external water tank, something that can contribute towards saving you money in the long run.Space: Combi Boilers take up less space in the property than standard boilers as there is no requirement for a separate hot water heater. This makes it a popular choice for residential properties where you can choose to have the single Combi Boiler unit installed in the corner of a basement, cupboard, roof space/ attic or in your garage.Performance: hot water is powerfully delivered via your taps or shower at mains pressure, helping you to enjoy a power shower. No hot water pump is required.Installation: A lot of time (and therefore money) can be saved when installing a Combi Boiler as only the one unit needs to be installed. Savings can also be made on the amount of piping that needs to be used when installing the boiler, as there is no need to plumb in a separate water tank located elsewhere in the property.Maintenance: Future maintenance costs are reduced as there is only 1 unit to maintain.
