Aztec Easyfit 12kW Boiler running costs

[CRob1974]

Good afternoon, we have just had an Aztec Easyfit 12kw installed and I'm a bit worried about running costs. I have calculated costs using an online calculator but this doesn't take into consideration the boiler will switch on and off when at full heat.

The tariff I am on is economy 7 at 7p per kwh and standard is 12p per kwh. We estate the radiators to be on roughly 16 hours per day during the winter months.

I have been told to fire the boiler up to the max during economy 7 time and would really appreciate any help you can give to keep costs down or maybe a rough estimate of costs.

Thank you for any help in advance

if your heating is on full for your stated hours it will cost a calculated £13.44 per day.
If you don't have gas have you considered a heat pump

Expensive springs to mind.

This was the sort of question to have asked prior to install

Hi, thanks for the reply... £13.44 a day = £403.02 a month, beginning to get more worried. We don't have gas here. I haven't heard of a heat pump, how does it work and does it fit to on the current system ?

Simply explained a heat pump is an electricity driven system which when installed correctly can give an efficient heating system comparable to natural gas

Thank you for the info.

You are welcome. There are many different heat pumps available just like boilers.
Your installer is the the main difference just like boilers

LPG is the alternative failing the electric route

lpg or oil i would go with lpg myself

I have just read that although the boiler says it is a 12kw it can be set to a 6 or 9kw. Is this true ? My wife seems to remember the plumber saying it was a 9kw but it says 12kw on the side.

Have a look at economy 10 instead of economy 7 its a tariff for wet electric heating.

This is definitely something I will look into, anything to keep costs down

A heat pump system is more costly to install but cheaper to run
A gas or oil boiler is cheaper to install but more costly to run

How well insulated is your loft? Building regs recommend a minimum depth of 270mm which would go a long way to improving the energy efficiency of your home. You could possibly still get this done free through the energy company obligation/affordable warmth schemes if they are still running.
