Is an Air Source Heat Pump efficient enough in a damp bungalow for someone who has disabilities?

Hi Everyone,

I just need some advice, our oil boiler was causing problems earlier on this year and has since been condemned. The council seem to want to fit us with an Air Source Heat Pump rather than an oil boiler....which I know the reasons for, but I am  not entirely sure whether this is going to be appropriate for the property where we live or for the fact  that my wife has disabilities and respiratory  problems. Our windows are draughty and we have had damp issues in the past. It is a very small bungalow admittedly, but will it be efficient enough in the winter months?  Can anyone advise me please? Many Thanks.

There are several things to consider when changing to a heat pump.
 

I assume you have radiators at the moment. The main difference between a heat pump and an oil (or gas) boiler is the temperature of the radiator system water. A heat pump will run most efficiently at less than 50 deg C, (so your radiators will feel warm but not hot). The oil boiler will probably take the radiator temperature up to 65 or 70 deg. Because of this you may need larger radiators, and the heat pump should run for much longer periods. Think of it as being on “tickover” rather than lots of accelerating and breaking. 

Likewise the hot water at your taps will not be 60 or 70 deg C, ours is about 50. The heat pump can’t heat the hot water at the same time as heating the radiators, so it’s best done when you don’t need the heating for an hour or so, either at night or during the warmest part of the day, or both. Mine runs at 3am and 12 noon. We have a 210 litre tank which is about 5ft high and there are 2 of us here.

A couple of questions for you: how do you heat your hot water at the moment, is it “on demand” or do you have a hot water cylinder? Assuming you have radiators how many are there?

@juliamc Thanks for the ping!

@Viv1966 I wish I could be more helpful, but I can only say that there are just so many factors involved that it really needs an expert on site to advise properly.

As regards what you were told by the OVO agent, of course he has access to a lot of information about your metering arrangement, which should put him in a position to make sensible suggestions. I really doubt, though, that it would take only a tariff change to set you up for making the best use of night storage heaters. It depends on precisely what sort of meter you have and what tariff you’re on currently. If your housing association say you need a new meter, this could well be true. 

If you’re up for it, a couple of photos taken with your smart phone would help us to see what’s what:

  • A close-up of the meter itself (with the display lit up by touching a button if necessary) clear enough to be able to read the display and the markings on the meter itself;
  • A view of the whole backboard so we can see the main supply cable coming in from outside, and all the cables to and from the meter itself;
  • If it’s not clear from the previous photo, a close-up of the meter exchange label - the card left by the engineer giving the numbers and readings of both the old and new meters (assuming he did leave one, as he’s supposed to do);
  • A view of the consumer unit (fuse box) clear enough to be able to read any labels the electrician may have left to say which breaker is which.

Sorry if that’s a bit daunting …

@Firedog Thank you so much for your reply.  Your suggestion sounds like a good idea, but there are two reasons why it may not be possible.   The first reason is that i cannot open the cupboard door to my smart meter, however i may! be  able to give you a meter number.  The other reason is that i mamaged to speak to Ryan a storage heater professional based at Ovo who is ringing me back thus Tuesday to let me know the process of how the changes take place. But if i gave you a meter number would that be ok??

Hiya ​@Viv1966, I hope you’re doing well - nice to see you back.

 

I do know a Ryan who works in the multi-rate meter side of the business - if it’s him you’re speaking to you’re definitely in good hands. Could you confirm why you’re not able to get into the cupboard? Just to confirm, our engineer will need access to this cupboard to be able to change the meter.

 

For ​@Firedog to help you, a meter number won’t suffice I’m afraid. Is the meter in a communal cupboard? If so, the Facilities Management for the property should be able to give you access.
