I am putting storage heaters into a two bed ground floor flat (one flat above).
Lounge 12.4 cubic metres, 2 outside walls Bedroom1 8.4 " " , 1 " " Bedroom2 5.7 " " , 1 " "
Ceiling about 2.5 metres.
Cavity walls have been insulated.
I am thinking five elnur 1.7 kW. Two in lounge, one in hall, one in each bedroom.
Will that be enough? The property is being rented so I would sooner it was too much rather than too little.
Thanks very much in advance.
They claim to be able to store about 12kWh - so if that were true, in simple terms they can average an output of 750W for the 16h they are not being charged.
However I doubt that is true. The volume of the whole heater is only 60L!
much rather than too little.
Storage heaters are almost always too little unless massively oversized.
Do the sums:
It's not usual to put storage heaters in bedrooms. They may overheat the bedroom at night, and bedrooms don't usually need much heat during the day. Panel heaters in the bedrooms will be using cheap rate lecky overnight anyway.
- 1 or 2 storage heaters in lounge, with either a decorative fire for evening top-up or something like a Dimplex Duoheat that incorporates a panel heater for evening top-up. These need both off-peak and peak wiring.
- 1 small storage heater in hall
- panel heater in each bedroom - get one with an electronic timer/stat that doesn't go whirr whirr click click all night.
- You can get small storage heaters rated for bathroom use (subject to zone) if desired, otherwise an electric towel rail.
If the tenants are likely to be out all day anyway then storage heaters might not be cost-effective.

s too much rather than too little.
The 1.7 refers to the rate of heat input. The output varies according to the design so you need to see the manufacturers tables.
Also, when it is in "output mode" , initially the output is much higher than when near "discharged"
So no-one can answer your question as the output varies between manufacturers. Some are higher output for a short period and some will be a lower output for a longer period.
Get the maximum circuits you think that you might need put in but the minimum number of heaters.
The circuits need to be Part P-ed, installing a heater onto the end of them doesn't, but the heater is the biggest part of the cost (by far).
Do you mean cubic metres? Those are tiny rooms if you do.
Even if you mean square metres, they are still not large. One in the lounge and one in the hallway (by the bathroom) should do it.
As another poster has said, put panel heaters in the bedrooms, SHs in bedrooms makes them much too warm to sleep in.
