Any energy performace experts: Night Store Heaters and energy performance certificate

Former Community Member

Any body else getting asked to put in Eco 7 and Dimplex Quantum heaters as a way of improving the EPC ratings of domestic rentals. 

Constantly we're being asked to take out decent 24hr Lot 20 heaters with stats and timers and replace them with the Quantum and having to put in new economy 7 supplies and DBs


For a lot of tenants it just pushes up the electricity bills because they have to have the Quantum on the full 7 hrs over night and then can't negotiate a low day rate with their supplier (you end up paying more on your day rate if you have Eco 7). It doesn't take in to account life styles. Some people out at work all day and are happy to have their 24hr heaters on for a couple of hours in the evening when they get in as oppsoed to having to use the full 7 hrs overnight.  And the cost of putting  these in runs in to 1000s which landlords just pass on back to their tenants


Properties with gas CH get better EPCs  than those with standard 24hr electric rads  but this doesn't make sense either as green generation increases each year  therefore why not just stick with decent electric rads that can be used 24hrs when the consumer wants and needs them.


 Am I missing something?

    I'm not actively putting in new storage heaters, but when an old one breaks down, we just change it for a new dual supply type, which meet the current energy use Regs.

    The Tenants see no difference in their bills - why would they, they need a house heating, just by changing the heater does not make it any cheaper to heat it.

    What we have been doing recently is removing Storage Heaters, and fitting Air Source Heat Pumps. Supposedly far more efficient than storage heaters, however, Tenants are saying their electric bills are actually going up, rather than down with ASHP in place. There are a number of other complaints about them, such as the noisy fan running all the time, and even the central heating type pump vibrating all night long. Some of these niggles could be fixed by better installation, but the use of them isnt universally regarded well.

    I think the main problem is that they are retro fitted to older houses, which dont have very good insulation, add in that most Tenants just cannot comprehend how to work the system correctly, and there is bound to be problems with them.

    We have Tenants who cannot work the dual supply storage heaters, so once they see the controls for the ASHP, it is well beyond their capabilities, which is a manufacturing design problem - if there is a need for a 20 page manual to show how a heating system works, then it is far too complicated.
