Energy Prices (Strictly NO referrals!)

[Nathan]

Just to update on this, it transpires that the person that originally posted the info had selected the economy 7 tariff by mistake and not realised it was comparing it to his current tariff (IOG)

Sorry for the false alarm.

Panic over haha

He paid a little over £1000 for all that. I'm assuming all the rest (X more thousand pounds) was basically paid by us (eg: energy bill green tarrifs)?

exactly - Starmer & crew need to think a little more competently than Tories to modify schemes (like ev too) so that in particular for HP's the middle men are not installing inappropriate
less efficient products to naive consumers just to get their hands on part of these funds (like the current scandals on bad home cavity+external insulation )
to also avoid the scenario when someone tries to sell the house and the HP heating system is criticized/marked-down on the survey, too.

[ e: a good read about heat pump installs I'd posted in hp thread https://media.nesta.org.uk/documents/How_to_reduce_the_cost_of_heat_pumps_v4_1.pdf

An improvement in the quality of heatpump installations to make them runmore efficiently in homes. We havemodelled efficiency improvements aseither: an installation enabling a 10ºCreduction in mean flow temperature belowthe typical 45-50ºC; or an exceptionallyefficient heat pump in a high-qualityinstallation (proxied by SPF of top 20 percent of installations). Achieving either ofthese efficiency improvements withoutsignificantly increasing current installationcosts could reduce the relative whole lifecost of heat pumps by £110 to £260 peryear. Lowering this temperature may beenabled by additional (or larger) heatemitters (radiators or ceiling/underfloor),reduction of heat loss rates throughimproved insulation, or higher massflow rates. See endnote63 or Table 6 forestimates based on low and high upgradecosts.

It could be a bit if a nightmare buying a house with a heat pump installed but without an upgrade to its insulation or radiator upgrades necessary to complement the system. EV charging is a relatively simple add on to a house but whole house heating and hot water requires more than an electrician to devise and certify.

Reality = the vast majority of installs are fine. You only hear about the dodgy ones because that is what sells adverts on your rag of choice.

The irony is the worst examples of utterly terrible installs I have seen are on new builds where there isn’t any grant funding available.

The issue that no one talks about is the vast majority of condensing boilers are also badly installed and materially under perform and yet no one seems to care.

You don’t need to upgrade your insulation for a heat pump, it has no bearing on its performance.

Now you should do the basics like loft insulation because you know energy prices are £lol but that’s irrespective of the heat source. Windows and doors are the other place to make good gains if you don’t have double glazing but they are expensive.

However going further is optional, retrofitting wall insulation isn’t risk free and no one’s going to recommend ripping up an uninsulated concrete floor to insulated it unless you are doing it for another reason, even when installing UFH, it’s not worth the hassle.

Most heat pumps can give you an indication of their performance on their controllers. The other obvious one is the size of the energy bill.

If consumers educated themselves on what a well for forming heating system looks like (gas or heat pump) they’d have lower bills and less problems.
