McDonald Engineers’ uncompromising approach to quality and performance has seen the company improve the standard specification of its THERMflow to be the very best in the market.
The units are manufactured from a minimum of 1mm thick copper and featuring an extended length secondary coil for all units with 9 or 12m of Finned Coil compared to other manufacturers who use 4.5 or 6m.
The changes are a significant increase in specification from many copper cylinder manufactures which tend to offer a standard Thermal Store manufactured from 0.7mm thick copper with far less coil surface area.
The units are supplied with a Check Valve, Y strainer, Mixing Valve, Jetseal Maintenance Free Ballvalve, Copper Float, Connecting Pipework and Immersed Cylinder Thermostat.
The increase in thickness of the copper, by as much as 75%, means the cylinders are far more resilient and cope far better with the daily rigours, such as aggressive water conditions.
When a sealed system primary coil is fitted, we use 9 or 12m of Finned Coil which reduces the heat up period and reduces boiler cycling with all its associated benefits.
