@writefirstdraft Great article, very insightful. I have thought for a long time that the government subsidies prop up the price of heat pumps. We saw this with PV, each time FIT tariffs feel so did the price of panels. I also heard of from a major supplier. Look at the cost of PV now.

#VauxhallLuton this is the price of not increasing fuel duty since 2010.

This is a really important part of the industry. Installation is often difficult but relatively simple if the basics are followed. Diagnosing faults or wrong settings needs a different level of skill. Good for you Mike. I know how much work you've put in to get to this stage.

In the past few weeks I’ve worked on Vaillant, Mitsubishi, Panasonic, Samsung, NIBE and Daikin heat pumps. I’m going to start videoing my findings because it is super interesting learning the nuances between how each heat pump works. Does anyone have any model specific questions?

@AbigailDombey @CrestNicholson If something costs a pound more they won't do it. It's all about profit.

@chrisdunham70 This is the only country with such a rule. They want us to keep burning the gas.

[William (Bill) Johnson @B_JohnsonBill]

@chrisdunham70 This was in a rushed permitted development regulation that was released in 2010 after the Tories got in power. At the same time they abandoned all incentives for heat pumps and delayed the RHI for 4 years. This was a clever move since small HPs are difficult to make quiet.

[William (Bill) Johnson @B_JohnsonBill]

@AbigailDombey There's also no requirement to inform DNOs about electric showers or induction hobs with amperage many times greater than heat pumps and are used at peak times.

@suburbanpirate @JeremyClimas @cbrookesheating @Patrickswheeler It costs £400 and hours of filling in online forms to get one model on the database. The minimum time to complete the process is 3 months. At the end of it you will need therapy. I urge manufacturers to limit the variations as it makes the whole process difficult and costly.

[William (Bill) Johnson @B_JohnsonBill]

@suburbanpirate @JeremyClimas @cbrookesheating @Patrickswheeler It seems to me that there assessor has to get all the details correct for a heat pump to rate good but as long as a boiler is gas and new it gets good. This is built in bias towards gas. Could this be another case of influence by the boiler manufacturers and has distributors?

@swebster56 @Damon_BPHR In 17 years of heat pumps I have only found about 10 houses that needed hybrid. The biggest reason is electricity supply not big enough not radiator temperature. Now the same houses are fitting 3ph for EV charging, problem solved.

BREAKING: Canada's brutal national police are again arresting Indigenous peoples trying to protect their own lands - this time the Pacheedaht nation in British Columbia. Brave reporting by Brandi Morin.

The RCMP has to be the most anti-Indigenous police force in the world.⤵️

@ejwwest @heatpolicyrich The government is keen to use market forces to push the transition but the rules still favour fossil fuel. There's been no positive publicity from HMG but lots of negative from Tory donor media who obviously have shares propping up the oil and gas industry.

Who would have thought that inflation was caused by #nurses, #Doctors and #rail workers spending lots of money after COVID and Brexit. If they get more money how exactly will that increase the price of coffee, petrol, bread, milk etc? Economics is clearly complicated.

@severs1966 @colinwalker79 Already happened in the early 70s.

[William (Bill) Johnson @B_JohnsonBill]

@colinwalker79 I did 5 years as apprentice mechanic, at the end there were so few jobs because of improvement in reliability I moved on. I am now a heat pump specialist at the start of a new industry. Mechanics make great heating technicians because they understand how things work.

@shmergel @heatpolicyrich Asap would be to late. Any new nuclear will take 20 years min. to get on line. And besides, there's only a finite amount of fuel.
