House with Trianco Aztec boiler

simontemplerthesaint666

Hello,

First time poster and nervous house buyer. Just about to purchase a house that has a Trianco Aztec electric heating and hot water system (wet system I think). I am hearing lots of stories about how much money it is going to cost me per month but I am not sure what to believe. The house is three bedroom semi and has no access to gas.

Is there anyone who has a similar system that can give a true idea of what monthly electricity bills are going to be like?

Thank you all for your time.

Hi - for us in a three-bed mid-terrace with an Elnur CMX15 electric boiler down-rated to 6Kw running six radiators and the hot water, our total monthly electricity bill is coming in at or less than £80 per month. Very good insulation is the key. No annual servicing required either and of course no gas standing charge. We have the heating set for ~05:30-07:00 at 20c then down to 14c and on again at 22c between 15:30-22:00. We have a smart (learning) chrono-stats. Hope that helps a little bit.

Ultimately electricity is the most expensive form of heating there is

Using the latest averaged figures from the Notts Energy Partnership website gas costs 4.6p per kwh whilst electricity costs 14.57p per kwh - ie. 300+% more. As such there is no doubt that if you are used to mains gas prices you will be in for a shock.

How much of a shock depends on a lot of factors such as insulation levels, the sort of temperature you like to keep your house at, whether it has Economy 7, etc etc. To a degree I think every home is unique and so whilst others may give you an idea you really won't know till the bills hit.

Whilst I don't want to frighten you I think you are very right to be concerned. If it's a deal-breaker then given that it's a buyers market I would ask the vendors to show you at least a year's worth of electricity bills so you can make an objective assessment.

I wish I had investigated this more thoroughly when we moved to our currently property (which was on LPG rather than electricity) as it led to us a couple of years down the line ripping out the LPG and replacing with oil. Had I known I probably would have tried to haggle on the price to take this work into account. But ultimately if the house ticks all your others boxes then it may be a price you are a prepared to pay.
