How efficient is the Heatslave II External 25/32?
The Worcester Bosch range of Heatslave II External boilers are 90% efficient which can help to save you money on your energy bills. A 90% efficiency means that for every £1 spent heating your home, only 10p is lost to waste gases produced during operation (this is something that happens with all oil and gas boilers). In addition to the high efficiency, Heatslave II External boilers have been awarded an ErP A-rating for heat and B-rating for hot water.
Is the output rating suitable for my home?
A 32 kW central heating output rating is ideal for 3 bedroom houses with around 15 radiators and 2 bathrooms.
What options are available in the Greenstar Heatslave II External range?
Greenstar Heatslave II External boilers are available in 3 different outputs and this 32 kW model is the most powerful. So, if your heating and hot water demands don't warrant such a powerful output then 18 kW and 25 kW models are also available.
Is a combi boiler suitable for my home?
Combi boilers provide heating and hot water on demand using the mains water supply. As a result, you'll need to ensure that your home has strong mains pressure, otherwise the water out of the tap will be weak.
How long is the warranty period?
Greenstar Heatslave II oil boilers come with a 2 year warranty as standard, which will see that you're covered after the installation. In addition, the primary heat exchanger comes with a warranty of 5 years.
What are the key features of the Heatslave II External 25/32?
As an external boiler the Heatslave II is housed in a green casing with IP45 protection to see that the unit is protected against the elements.
The features of this boiler are well worth protecting as they include an eco hot water mode to lower energy usage and keep your energy bills to a minimum, frost protection to keep it running through the cold winter months and it can fill a kitchen sink with hot water in only 22 seconds.
How big is the Heatslave II External?
The Heatslave II External has dimensions of 950 x 640 x 770mm (HxWxD)and as an outdoor combi boiler you'll be saving plenty of room in your property.
