Ok, bear with me. I have a thick question but my plumbing knowledge is as deep as a teaspoon.
We have a Baxi Luna hydronic system suppling our hot water & heat. For the past two weeks, it's been 'tripping', eg pilot light extinguishes and needs to be reset (if that's the right word). I called a plumber out after a few cold showers and he diagnosed pressure as the problem, adjusted it marginally and left. Hoped this would fix it, but I had doubts it was the cause as the pressure setting hasn't been adjusted in the past three years.
Today, I realized nearly all of the radiator valves in the household had been turned off. My genius housemate had apparently turned them off two weeks ago (it's summer currently so I didn't notice) because he couldn't figure out how to adjust the heat setting. That's cool and all, but good lord I wish instead of putting effort into complaining about the travesty of brushing his teeth with cold water, he could have just put put two and two together and realized that the gas powered hot water issue started the same day he messed with the gas powered radiators.
Anyways, look, I myself am no genius. I have next to no idea how hydronic systems work. I do want to understand however WHY it would trip if the radiator valves are closed. I feel it's something like closing the valves means there's less water to heat which causes it to overheat and trip a sensor to shut down? Also, does the original plumbers logic still stand - perhaps closing the valves affects the pressure, if so, why is pressure important?
Apologies, I'm aware these are somewhat thick questions but I'm coming from a point of no knowledge!
