Supplying modern A-rated regular (heat-only) boilers directly to Glasgow properties with existing open-vented systems. Direct like-for-like replacement without disturbing vintage radiator circuits.
In many older Glasgow properties—especially Victorian sandstone flats with vintage microbore or buried copper pipework—converting to a 1.5-bar sealed combi can trigger joint leaks. A direct regular replacement is the safest, fastest choice.
Because regular systems run under low gravity head pressure rather than high mains pressure, your historic radiators and hidden pipe joints are safeguarded against sudden pressure blowouts.
Replacing an old heat-only boiler with a modern condensing equivalent requires zero tank decommissioning or loft pipe removal, typically taking just 4–6 hours with minimum household downtime.
If your gas supply is ever interrupted, the electric immersion element inside your hot water cylinder guarantees your family always has access to hot water.
