Combi Boiler Installation
Combi boilers are a good option for flats or houses with only one bathroom. They work by providing heat for your radiators and heating water on demand. This negates the need for space for a cylinder or any tanks. When you turn on your hot tap, the movement of the water through the boiler will operate a flow switch. This fires up the boiler and heats the water as it flows through the heat exchanger. Combis can use a lot of gas for short periods. The supply needs to be large enough to carry the required amount of gas. A competent boiler installer will be able to give you the advice you need.
Trust the Gas Safe register for a boiler installer
A Gas Safe registered engineer will be able to calculate if your gas supply is adequate or needs to be upgraded. In many cases installers have connected combi boilers to a gas supply designed for a conventional boiler. The inadequate supply of gas will lead to poor performance of your boiler. This has earnt them an unfair reputation as a second rate option for heating your water. An inadequate gas supply to your boiler can also be dangerous and possibly lead to explosive ignition, burner flames extinguishing and incomplete combustion, which can produce carbon monoxide.
Although combi boilers are convenient, they do have their limitations. A combi boiler will typically provide a 35 degree Celsius rise in temperature on the incoming mains water. In winter times incoming mains temperature can drop to 5 degrees so you will be supplied with 40 degree water; in summer time when the mains could be as warm as 15 degrees so you will get 50 degree water. The KW of your boiler gives you your output. At the smaller end of the spectrum a 24KW combi boiler will provide around 9 litres of hot water per minute, whereas a larger 35KW combi boiler will typically produce around 15 litres per minute. Of course it is worth bearing in mind that to produce these rates you must have at least that amount of water available through the mains in the first place.
