I looked at mine again.
| Hot water | From main system, no cylinder thermostat | Poor |
|---|
Well it also has an immersion heater which does have a thermostat, the central heating does heat the DHW in the winter, but can't see how a cylinder thermostat will really change amount of energy used?
| Lighting | Low energy lighting in 23% of fixed outlets | Poor |
|---|
Like to know what was in the other 77% as all are either CFL or LED.
An average household would need to spend £1,130 per year on heating, hot water and lighting in this property. These costs usually make up the majority of your energy bills.
You could save £163 per year if you complete the suggested steps for improving this property’s energy rating.
Well not far off with cost of oil but then the list.
Step 1: Floor insulation (solid floor) 83 years to break even. (2 points)
Step 2: Low energy lighting less than 1 year, but already done. (1 point)
Step 3: Solar water heating. 68 years to break even. (3 points)
Step 4: Solar photovoltaic panels, 2.5 kWp. 17 years to break even. (6 points)
But last two don't make any sense. If you fit solar photovoltaic panels then they can heat the water, so it would be pointless to fit both. I would need it seems 12 points to get to next band, and with the info it gives, that could not be done at a reasonable cost, so to try and get next band does seem pointless pun intended.
I have it would seem gained 10 points with LED lighting, and solar panels which also heat DHW. Electric wise, I am about net-zero, around £150 per year, which is in the main due to standing charge, so it is just the oil bill.
Under the main house is a flat, and the EPC for this says:-
Step 2: Hot water cylinder insulation. (1 point) but it does not have a hot water cylinder, it draws hot water from the house above it.
Step 4: Hot water cylinder thermostat. (1 point) but as above it does not have a hot water cylinder.
Step 5: Heating controls (room thermostat). (2 points) but it has a room thermostat, it was the house above it which had no thermostat.
Again no way would it pay to do any improvements, and can't understand why anyone would have treated the flat and main house as seprate abodes, both the oil and electric is common to both.
