What is the Vaillant range suitable for?
Vaillant specialise in combi and system boilers, with a wide range available to suit different size homes and heat and hot water demands. When choosing your new boiler, you need to firstly consider what is the most suitable type and size of boiler for your home, heat and hot water demands. The most popular type of boiler in the UK is the gas condensing combi bioler, this is mostly due to their small compact size & overall efficiency in comparison to the other options. Combi's are typically suited to small to medium sized properties as if you have a larger home then you may require a higher demand for hot water in which a combi may struggle with as the pressure drops if there is more than one hot tap on at once.
The kW output is determined by the size of your house and number of radiators; generally, the higher the kW output of a boiler, the more demand for hot water it can cope with. If you need help determining what kW output you require for your Vaillant boiler, you can use the following as a guide:
| 24-27kW | 28-34kW | 35-42kW |
|---|---|---|
| 1-2 bedroom | 3-4 bedroom | 4+ bedrooms |
| 10 radiators | 15 radiators | 20 radiators |
| 1 bathroom | 1-2 bathrooms | 2+ bathrooms |
