In this trailer for the Gas Engineer Podcast, host Tulloch Priest (introduced as Tullik Priest) is joined by Luke from Addithermal, OFTEC‑registered oil technician Holly Stallworthy, and former Gas Safe inspector Terry Sawyer. The conversation covers three main strands. First, Terry explains a common misunderstanding that a lack of opening windows automatically means a gas safety failure, clarifying that window opening is a building‑regulation issue related to moisture and heat buildup, not gas safety. Second, the hosts discuss the financial dilemma faced by tradespeople: whether to stay in a lower‑paying job they love or switch to higher‑earning work to afford life milestones like buying a house or holidays. Third, Tulloch highlights the challenge of expanding heat‑pump adoption in the UK, noting that electricity costs are roughly four times higher than gas, and that most existing housing stock is built for gas‑boiler pipework and radiators, creating a barrier to heat‑pump proliferation. The tone is conversational and candid, with a mix of informative clarification, personal reflection, and industry‑focused concern.

This is the Gas Engineer Podcast. I'm your host, Tullik Priest, and today we're joined by Luke from Addithermal.
Holly Stallworthy, an OFTEC registered oil technician. Terry Sawyer, a former Gas Safe inspector.
Yeah, so there's little things like that where I still get phone calls saying, oh, there's no opening windows, that means it's failed a gas safety.
I said, no, the opening window has nothing to do with gas safety.
The opening window is to do with moisture and heat buildup. It's a building regulation. So he said, well, why do they drum it into you at training school then? I said, because they don't know either. I only found that out working for Gas Safe. I then had to make decision in myself.
Do I have no money but do the job that I love, or do I try something else which gives me more money to buy a house, go on holidays, you know, live, that sort of thing? And the reality is completely different because life requires money.
200% efficient sounds great until you realize that electricity in this country is 4 times the price of gas. So I mean, the, the problem we're trying to solve is how do we increase the proliferation of heat pumps? But we have a challenge in the UK, which is that we've got older buildings with pipework and radiators that's been designed for this been designed for gas boilers.
