You can now heat up your existing radiators or floor heating with electricity using our electric central heating boiler. You no longer require gas, so zero chance of carbon monoxide poisoning nor do you require a flue gas outlet. The microprocessor controlled electronics make this a very energy efficient unit. It is a very low maintenance unit that does not require annual servicing like a gas-fired unit. 

4 and 6kW units use single phase (230 Vac) electricity and can be connected to your existing circuit board. Always check if you have sufficient amperage available on the circuit fuse you’d like to connect to.  9kW and over require a 3-phase electricity, power current. 

You can use green energy to run the electric central heating boiler or use your solar panels to provide energy to the unit. A very eco-friendly unit indeed. 

We have sold the Eltherm electric central heating boilers for 3 years and have never had any returns or problems. The Eltherm electric central heating boilers were installed in several large projects in Dubai, Macau and Qatar such as; the Damac Towers (Dubai), Le Meridien (Dubai), the St. Regis (Dubai), the MGM Cotau (Macau) and the Mandarin Oriental (Qatar).

We decided to replace our gas-fired central heating boiler with an electric unit as we have installed solar panels. Now we no longer require gas. Clear instructions so very easy to install. For warm water we purchased a Wesen 80 liter. We are very happy with the service provided by Waterheaterstore.
