A boiler that has sat idle since April will tell you everything that is wrong with it in the first two weeks of October.
Why hydronic matters here
Hydronic and radiant heating is far more common on the North Shore and in older West Vancouver homes than in most of the Lower Mainland. It is a good system — even, quiet, comfortable — and it is unforgiving of neglect, because the problems develop slowly and invisibly inside a sealed loop.
What a service should cover
- System pressure — checked cold, and the cause investigated if it has dropped, because a system that loses pressure is losing water somewhere
- Expansion vessel — the most commonly neglected component, and the usual reason a system keeps losing pressure
- Circulation — pump operation, and whether every zone and every radiator is actually getting heat
- Bleeding and air — air in the system is both noisy and inefficient
- Controls and thermostats — zone valves are a frequent silent failure
- Combustion and venting on a gas appliance, with the flue checked
- Relief valve operation
The autumn argument
Plumbers and heating technicians are busiest in December and January, because that is when no-heat calls land. A service appointment in September or October is a scheduled visit at a normal rate. The same fault found on 2 January is an emergency call-out, probably at a weekend, probably with a part that has to be ordered.
If your system is more than fifteen years old, autumn is also the sensible time to have an honest conversation about replacement rather than another repair — while you still have the option of planning it.
What it costs you to wait
No heat in January is not just uncomfortable. In a sustained cold snap an unheated house is also a freeze risk for the plumbing, which turns a heating problem into a water damage problem.
