Is a Viessmann Vitotron 100 Single Phase 4-8kW electric boiler suitable for my home?

If you're looking for the best electric boiler for your small home, then you should certainly consider the Viessmann Vitotron 100 Single Phase 4-8kW electric boiler. This highly efficient electric boiler can provide instant heating and hot water to homes with up to 10 radiators, and with 1 bathroom. This boiler operates alongside an external hot water storage cylinder, meaning it can provide plenty of hot water to your home's taps and outlets, without compromising water pressure.

With an electric boiler, you will save time and money on installation, since there are less additional components (such as fuel tanks or flue pipes) to put in place. This also means you'll live free from the risk of any gas leaks, and, without any internal combustion of fossil fuels, you'll reduce your home's overall carbon footprint.

What is the output range on a Viessmann Vitotron 100 Single Phase?

The Vitotron 100 Single Phase comes with an adjustable output range from 4kW, to 6kW, and to a maximum of 8kW. This is a single-phase boiler, meaning it is best suited to homes with lower energy demands and a single-phase electricity supply.

Homes with higher heating and hot water demands, and with a three-phase electricity supply should instead consider the Vitotron 100 Three Phase 4-24kw Electric Boiler.

Your home may require an upgrade from single-phase, to three-phase, depending on your home's energy demands. However, you should first seek advice from an electric heating engineer as to whether such an upgrade is necessary.

Viessmann Vitotron 100 Single Phase 4-8kW boiler dimensions

What is the size of the Viessmann Vitotron 100 Single Phase 4-8kW electric boiler?

If you'd like to fit your boiler in a kitchen cupboard, the Vitotron 100 Single Phase 4-8kW has ideal dimensions to do so. With a height of 716mm, width of 316mm, depth of 235mm, and weighing in at a low lift weight of 20.5kg, this boiler is simple to install and conceal. What's more, without a flue pipe, you also have the freedom to install it anywhere in your home.

Viessmann Vitotron 100 Single Phase 4-8kW electric boiler price

This electric boiler typically costs £1,127, including VAT. Alongside the cost to install, as well as any sundries, this will likely bring the total costs to somewhere between £1,927 - £2,427.

For installation, you can expect to pay between £500 - £1,000. Installation tends to have the most significant influence over the total price, given that the costs depend on many factors. Generally, the more parts and labour required to carry out an installation job, the more costs will start to climb.

Luckily, an electric boiler is rather simple to install. Having said that, if you are replacing an existing gas, or oil boiler, then you can expect the replacement to take some time, as any existing components and extra pipework will have to be removed.

Sundries covers any optional add-ons that you can consider as part of your installation, such as a system power flush. Sundries will likely cost up to £300. Your boiler installer will always discuss these options with you beforehand.
