Wanna know about heat pump cycling and why it's all to do with the minimum modulation of your heat pump and heat loss/demand of your house. 👍
It's that time of the year again and people ask about their heat pump "cycling". So in this new video, I've tried to explain the process and why in most cases, it's totally normal. Why Your Heat Pump Keeps Turning On And Off (It's Normal) youtu.be/hUWipv8SwsU

Reports suggest heat pump grants could be cut to fund defence. Why weaken a route away from gas and oil? What about homeowners, installers and UK manufacturing? Should grants stay, shrink or be better targeted? My take in the new video 👇 youtu.be/r05k5ZwrTZk

Me again. This time, like some sort of investigative journalist. 😆
Could electricity tariffs eventually be priced by device? The newer Intelligent @OctopusEnergy Go API now separates home & EV rates with new & different endpoints. Could it point towards EV, heat pump, battery & home all having different prices? youtu.be/LLmKa1V9rvI

Might be one fo you @sarah_go_green and other folks on Gas Boilers looking to potentially save some money on your bills. 👍
New video looking at a really simple question: Does turning your boiler flow temperature down actually save money? I explain what flow and return temperatures are and why it's the temperature of the water coming back to the boiler that matters. youtu.be/pegUvCXapU8

Heat pump vs oil boiler. Same house. Same 12,000 kWh of useful heat. Oil at 85% efficiency. Gas at 85%. Heat pumps at COP 3.0, 3.5 and 4. One of the results is much closer than you might expect.

New Video: Oil boiler vs heat pump, using the same 12,000 kWh of useful heat. At today’s prices: Oil 85%: £1,364 Gas 85%: £1,130 Heat pump SPF 3: £1,053 SPF 4: £790 The real comparison is the cost of useful heat, not the headline fuel price. youtu.be/SKgBTioDoUo

I changed 9 radiators when my heat pump went in. It helped me get down to lower flow temperatures and my 2025 heating COP was 4.2. But would I change all nine again? Probably not. There's a cost to chasing the difference between a good COP and a really good one.

I love pouring over the data for deep dives like this. 😍
I changed nine radiators when my heat pump went in. Looking back, I’m not sure I needed to. Using my 2025 data, dropping from COP 4.2 to 3.5 would only add about £87/year. That changes how you think about bigger radiators, upfront cost and chasing COP. youtu.be/KfBJ3zOb0w0
