Heat Pumps Will Work Just Fine In Scotland - In Summer
Paul Homewood has called it a Gerald Ratner moment!
A major heat pump supplier has attacked SNP-Green plans to use them to replace gas boilers in Scotland, warning parts of the country are too cold for them to work.
Lord Willie Haughey, the business tycoon, said the heating system is unsuitable for the Scottish climate as its performance declines markedly in freezing weather.
The Labour peer said some units can stop working properly at temperatures of -5C (23F), or require more electricity to function properly, resulting in higher bills.
The Scottish government plans to make it hard to sell your home if you’ve got an efficient gas boiler fitted, as opposed to an inefficient, noisy, ugly air source heat pump:
His intervention came after Patrick Harvie, a Scottish Green minister, last week unveiled plans for homes to receive lower environmental ratings if they are heated using gas boilers.
From 2025, homes will need to achieve an EPC rating of C or above at certain trigger points, including a sale, meaning some properties with boilers will be barred from being put on the market.
Lord Haughey, who made his millions through a global refrigeration business, said:”I have a heat pump company and following Patrick Harvie’s announcement, I should really be jumping for joy.
“But the truth of the matter is that heat pumps don’t work as efficiently in Scotland as they do in other countries.”
He said this was because of the colder climate and warned “legionnaires’ disease can thrive in lower temperatures in hot water systems”.
Lord Haughey added: “My staff are always telling me I should not criticise our core business but this is eco nonsense being peddled by the Greens. I’d like to challenge Patrick Harvie to a debate on the science of it.”
The tycoon also said the heat pumps are so noisy, that if eight or ten neighbouring homes had one, the resulting sound would “rattle your windows”.
He described them as “ugly and cumbersome” and said they created a bigger scar on a home than a satellite dish.
The thing is though, air source heat pumps will work just fine to keep you warm in the Scottish summer. Here’s today’s forecast from the Met Office:
Perhaps not such a Gerald Ratner moment after all!
