Warmhaus Enerwa Plus Combi Boiler

Warmhaus Enerwa Plus Combi

The Warmhaus Enerwa Plus Combi is the ideal choice for small to medium-sized homes.

Suitable for homes with little storage space, the modern-looking Warmhaus Enerwa Plus Combi is a wall-hung gas boiler that has compact dimensions and can fit in narrow places. This boiler is available in three outputs and can run on natural gas or LPG to meet the needs of most small to medium-sized homes. It also has an affordable price tag, some excellent features and an impressive energy efficiency rating.

How Much Does this Boiler Cost?

The Warmhaus Enerwa Plus Combi is a reasonably priced boiler and will set you back anything between £645 and £780, including VAT. It can be purchased with an output of 24kW, 28kW or 32kW to suit your heating and hot water requirements, with the highest output model coming in at the most expensive of the three. You also need to pay for the installation, so be sure to get a fixed-price quote from a range of installers to enable you to compare prices and find the best deal.

How will I know if this Boiler is Suitable for My Home?

Like all other combi boilers, the Warmhaus Enerwa Plus Combi takes water directly from the mains and doesn’t need to be installed alongside tanks in the loft or a hot water storage cylinder in the airing cupboard. Since no additional components are needed, this wall-hung boiler is perfect for homes where space is limited. It’s also a good choice for small to medium-sized homes with one bathroom.

You must pick the correct size boiler for your home, otherwise, you could end up with an undersized boiler that won’t heat your home properly or an oversized boiler that will cost more to purchase and run. As there is no one-size-fits-all solution, you should ask a local Gas Safe engineer to help you make the right choice between the 24kW, 28kW or 32kW Warmhaus Enerwa Plus Combi.

Is it a High Efficiency Boiler?

Yes. The Warmhaus Enerwa Plus Combi has been given an A-class energy label and has an efficiency rating of 92%. It comes complete with a gas adaptive feature and lets you adjust the boiler altitude settings to provide maximum efficiency. This boiler has a wide 1:10 modulation ratio as well, which also helps to improve efficiencies and save you money on your gas bills.

Does this Boiler have a Good Range of Controls and Features?

It does. In addition to the gas adaptive feature and wide modulation ration, the Warmhaus Enerwa Plus Combi has an insulated body, a stainless steel heat exchanger, simultaneous double-tap hot water capacity and an 8-litre expansion tank. It comes with an LCD control panel with 6 push buttons, visuals of heating and hot water temperature, flame modulation indicator and an auto-diagnosis codes and identification system. What’s more, the boiler is quiet in operation and boasts low heat loss, low gas and electricity consumption and continuous productivity up to 108%.

How long is the Warranty on this Boiler?

Warmhaus’s Enerwa Plus Combi comes with a 2-year warranty as standard, which must be registered within 30 days of the installation date.
