Many landlords have removed aging Night storage heaters and replaced them with direct electric radiators. Whilst this type of radiator has superb controls and timers, heat response time, is attractive and easy to install, PLEASE be clear that your EPC rating will plummet as a result. Landlords will remember that by 2018, premises that do not attain a minimum E rating cannot be rented out. DCLG view these heaters as ‘Peak heaters’ using peak rate electricity usually at least twice the cost of ‘off peak’ Economy 7 and 10 rates.
E7 night store heating has seldom been praised in my experience; too hot when you do not need it, cold when you do in the evening. Dimplex have been working on this problem and created the new ‘Quantum’ high heat retention storage heaters which, whilst expensive are in a different league to older style storage heaters, and appear to have addressed all the weaknesses. Beware of getting rid of your ‘E7 dual meter, especially if you have an older property and a large hot water cylinder.
