Better access, different problems
Compared with Wilmington's attached housing, heaters here are usually easy to reach — which removes access as a constraint and lets the diagnosis focus entirely on the fault. It also means replacements are more straightforward, and there is often room to consider a different configuration rather than a strict like-for-like swap.
Closed systems are the norm
Pressure-reducing valves and backflow prevention are common on service connections in this housing. That makes thermal expansion a live issue on almost every property, and it is the most frequent reason a relief valve starts discharging on a heater that is otherwise fine.
A correctly sized expansion tank, charged to the actual static pressure at the house rather than to its factory setting, is the fix. Tanks that were fitted years ago and never checked are frequently waterlogged and doing nothing.
Garage and utility room installations
Heaters in garages need correct clearance and, in many configurations, elevation of ignition sources. They are also exposed to colder ambient temperatures in winter, which lengthens recovery and can freeze nearby pipework in an unheated bay.

Questions we get asked
Why does my relief valve discharge every evening?
That timing usually matches the heater's main daily cycle. On a closed system, pressure climbs each time the heater fires, and without a working expansion tank the relief valve is the only outlet.
Does a water heater in an unheated garage need anything special?
Clearances and ignition source height matter, and cold ambient temperatures lengthen recovery times. Exposed pipework in an unheated bay is also worth insulating before winter.
