The first floor will be one third terrace, with glass balcony and country views - so plenty room for table & chairs.

You need to get someone else to do the EPC. The modern ones want internal wall insulation, floor insulation, solar panels and wind turbines!


Crazy isn't it! Apparently if I followed the recommendations I'd save 150pa!

I do actually have internal wall insulation on one side of the house but that apparently didn't count

Don't be fooled by the magic heaters with 'moon dust' in them - 1Kw of electricity will give out 1Kw of heat whether you use a simple 20 heater from Argos or a 500 (?) Fishler (for example) one.
.


I beg to differ. Take a look at the Rointe D series. They are very low energy to run but provide excellent heating.


Differ away if you wish Laughing but the simple laws of science decree that, with electricity (*) input = output

* = excluding A/C or Air Source systems

Glad to read about a balcony.
Still looks like electricity is the only answer for heating and hot water.

The reason they may be more efficient is that they can deliver heat instantly, thermostatic and timed. So depending on your lifestyle, they can be efficient - for example if you are out most of the day and only want to heat a room to exactly 20 degrees between 6 and 9pm mon-fri and another room heating to 8 degrees at different times and days of the week - storage heaters and central heating systems cannot do this efficiently with varying room occupancy and so people will tend to have the heating on in all the rooms even if it's only needed in one room.

Rointe D use a combination of convected heat and radiated heat. There are several other reasons why they are more efficient than standard radiators - I did suggest readers take a look....

IMO EPCs will require a review in / after 2025 when gas boilers will no longer be fitted into new builds.

Rointe heaters are more effective than standard electric heaters ie they warm the room quicker and more evenly. If you need to heat a room quickly and are then are going out, it will cost less than the standard electric radiator which you would have to turn on earlier and would continue to produce heat long after you'd left. But depending on your requirements and how you use it, it may not make a great deal of difference.

Efficiency is the amount of heat produced for the amount of heat input. All electric heaters are 100% efficient. Gas boilers are less efficient as lots of the heat goes up the chimney etc. Heat pumps are about 300% efficient - 1 kW of energy produces 3kW of heat.

But with 'leccy being three times the price of gas, efficiency and cost are different! Smile

We have an 12KW electric boiler (Sadia Heatrae) this works with a standard hot tank and radiators. It works very well but can be expensive in the winter. Summer is OK as it is just hot water (15 a week for a 3 bed 2 bath barn conversion).

We get quite a lot of bookings over the winter, our costs are about 1,100 a year.

Ideally I would add air source heat pump or solar for water but not too easy for us.
