I moved in to a house last year that has a Boilermate 2000 installed. After reading about them, I wasn't exactly thrilled about it, but we liked the house so decided to proceed anyway. In the first couple of months we were spending no more than £20 per month on gas. When the temperature started to drop around November-December we set the heating to come on for a couple of hours per day with only two of the radiators in the house being turned on. I was surprised at how much this cost for a small modern house with only two occupants as the monthly gas cost increased to around £50 per month.

In mid January we turned the heating off the timer and only used it a couple of times. My most recent bill that covers Jan 16th - Feb 16th says we used £65 worth of gas though. I don't understand how it has increased so significantly when our usage dropped so much. During this month, we also had a smart meter installed, and I assumed it was some kind of issue with the readings being recorded incorrectly. I contacted the supplier though and they insist there's no issue in that regard.

Our gas usage pretty much consists of a couple of showers per day and occasionally using a gas hob on an evening. I expected the cost to go up a bit in the winter regardless of central heating usage, due to the colder temperatures causing more heat loss from the system, but it still seems excessive. The smart meter isn't much help as it gives limited detail in the readings. It just shows I'm using a relatively consistent amount day-to-day.

Are these units usually that expensive to run? Does anyone have any idea why the cost may have increased despite my usage decreasing? Thanks in advance.
 
your heating an awful lot of water first just to get hot water before you even start using the heating
 
I would like to get rid of it and have a regular combi boiler installed, but I just don't think I could afford that at the moment.
 
Does it have a separate boiler or is one of the self firing thermal stores ?
It may be that you have it set to maintain the store temperature continually & the timer is just switching the heating pump on & off.
Do you understand how these thermal stores work?
 
I have a basic understanding of how they work. There's a separate boiler in the kitchen. It's called an Ideal Classic or something.

gledhill boilermate with seperate boiler heating store excessive if all you need to run is a shower and then wait for it to heat up and do heating

ideal classic old workhorse boiler, pretty reliable but not what youd call efficient anymore
 
I do understand it's not a very efficient system and it's not suitable for my needs and I will hopefully be in a position to get it replaced at some point. Does anyone have any idea why my gas cost would have increased by 30% when my central heating usage reduced significantly? I'm taking a meter reading every day now to try and gauge my usage, but I'm not sure if it could be indicative of some kind of fault.

From memory the store temp is set to 70c. Make sure your running the boiler on its max setting or it won’t satisfy the store demand and just run for however long you have it timed for

As above, you need to leave in on all the time & have the boiler stat on max the store will need to be heated to 70deg C for it to work efficiently it might sound counterintuitive but try it for a couple of days & keep taking the gas readings. You will use more until it is heated up but then it will settle down to just maintain the standing losses. The timer just controls the central heating pump which draws primary water from the store to the rads.

Hot water to the taps is only heated when the hot tap is opened.
 
I'd prefer a thermal store any day to a combi. Sadly misunderstood by most and therefore not used correctly or ousted due to lack of knowledge. Thermal store far outstrips the hot water performance of any combi boiler both on flow rate and consumption.

I agree Vee.
I went to look at 2x Harcopak's that could ideally be replaced with one as not a chance of getting a discharge waste installed.
Whose all electric store would you recommend?
