What kind of boiler is the Baxi 400 418 - standard, combi or system?

If you are searching for a heat only boiler for your house or flat, the Baxi 400 418 is certainly one to consider.

You may hear a heat only boiler described as a standard boiler, a regular boiler, or a conventional boiler but the terms mean the same. Heat only boilers require a hot water cylinder (usually stored in a landing or airing cupboard) and a cold water storage tank (usually stored in the loft) to operate. Your water is kept warm by the hot water cylinder throughout the day.

A heat only boiler lets you schedule the hot water and central heating you want for set times of the day. However, you'll have to wait before having a bath or shower if you forget to set it and there's no hot water left in the tank.

If you have a bigger family or more than one bathroom, a heat only boiler is a better option than a combi boiler in many cases. This is because a combi boiler struggles to maintain water volume, pressure and temperature to multiple points in a home simultaneously.

To determine that, we need to consider the size of the boiler. Size doesn't mean how big it is - it means how big its "output" is.

Boiler output is measured in kilowatts and tells you how much power a boiler can use to heat the water your taps, showers and radiators need. The higher the output, the more power it has.

When choosing a boiler, you should choose one that can cope with the peak demand for hot water in your home and not just your typical usage.

If its output is too low, sometimes your hot water will not be hot enough, but if your boiler's output is too high for your needs, your gas bills will go up and not down.
