47KG LPG bottle gas vs. Air to water pump

tee-bee_2

Hi all,

We're planning to purchase a 3 bed semi-D located in a village which does not have mains gas.

The current property has 6 x 47Kg LPG bottle gas, unfortunately the place has no space for a bulk tank. Calor charges £63 per bottle inc. delivery. The gas is used for only central heating & hot water. Cooker runs on electric.

Can anyone share their experience with LPG bottle gas? How many bottles do you consume annually? Esp. during the winter period?

As the boiler is very old late 1970s Potteron.. so there is the option to move from LPG to air to water heat pump.

Can anyone also share their experience with that as well?

Thanks

BTW, there will only be 2 persons in the property. We envisage having the heating on for 6 hrs during working days and the weekend total of 24 hrs during winter.

Forget LPG bottles, unless you are very rich!!! We used to go through 2 in 2 weeks in a 40 sq mtr appartment in the winter.
You could get a ASHP with the LPG as a backup source connected.

47kg of gas is about 650kW of energy your old boiler might be 70% efficient. So for your £63 you get 455 kW of heat for the heating or hot water. (by the way a new boiler would be 90% efficient)

£63 gets you 484kW of electricity (at 13 p a unit) so you are better off using direct electric heating (which is 100% efficient) than the old LPG boiler.

If you go for a ASHP your £63 gets turned into 1210kW (if the heat pump has a COP of 2.5, 250% efficient).

So I would go ASHP, with a wood burner for cold days, when the ASHP will struggle to get good COP.

The property is a 1976 semi-d with a chimney located in the Thames Valley. It's not massive, there is a chimney and wood fireplace.

Is it then possible to "link up" the existing fireplace to the current LPG gas central heating set-up?

Has anyone done something like this?

That's one thing we thought about doing but could not get anyone to do it. Looking back it would have been absolute madness...

LPG is stupidly expensive and so is wood unless you can source your own then cut it up etc. What a lot of people don't realise is that over a winter period you use more wood than you can probably collect...

For what its worth here is my real world experience...


LPG Bottles for CH :eek: prepare for a shock then and start looking to change your CH in time for the next winter...

We had an old Potterton boiler but on a bulk tank and jeez the cost of running it over a severe winter!!!!!!!!!!!!!!!! It was so bad we thought about selling the house but then discovered ASHPs as friends and neighbors have them so we got one and never looked back

There is a lot of negative stuff on this thread about them which is not my/friends/neighbors experience of them...

I also don't get this obsession of COP either... The system runs for 12 months a year and say 2-3 months of these are less efficient/more expensive in winter than the other 9-10 months when it costs buttons to maintain the property at a comfortable temperature with as much DHW as you can handle then so what...

All heating systems are more expensive in winter especially Electric/Oil/LPG... For example... Oil you could spend £400-500 a month in a severe winter for a large 4 bed house. Storage Heaters in a two bed property say £1000 for the winter quarter. Bulk LPG £350 a month for little used system in a two bed house which was still cold. These figs are from the last winter from people I know.

Of course as part of installing pretty much any renewable heat source you will have to insulate more but you will be glad you did.

I would add that heat pumps may not be money saving in the true sense but if you are off grid and want a comfortable lifestyle it is the way to go.

Real world experience - If I pop into a friends house with an ASHP at any time of the year, even -16c, house is lovely and warm whereas if I pop in and see a friend on oil the house is always cold and they moan how dear it is. Never had anyone moan about how dear the leccy is for an ASHP. I'd rather be sitting at 21c with the log burner on just for the fun of the flames than have oil/lpg and heat to 16c and sit in jumpers, stuff that...

All I can say is do your rersearch thoroughly, go and see some installed systems, choose a good installer and you will be fine. They are not rocket sience...


Que - the nay sayers how live on mains gas and don't have ASHPs

PS I removed a lot of my old posts re ASHPs as I got fed up with the baragage on negativity here.

Can you provide a description of your ASHP set up? is it air to water?

What sort of equipment/brand and how much did you spend on the installation and annual costs of running it?

Thanks
