I rent out a house. The boiler there is old (20ish), and a terrible brand - plumbers groan when they see it. Cost little initially (apparently - I was in school when it was new) but with expensive parts. Heatline?
Every few months there's something else wrong - most recently it was £70 "to re-connect filling loop and re-pressurise boiler and re-set", but within a month the tenant got in touch to say she's having to re-pressurise the boiler weekly.
I can arrange another plumber visit, but is it worth it or would you bite the bullet and install a new (£1800, I've been quoted) boiler and be done with it?
I don't want the tenant stuck with a faulty boiler, I just can't figure out how big an issue this is and what the correct course of action is. And I want this sorted fully before the weather turns, for her sake.
