Vaillant Commercial Controls

Vaillant Commercial Controls. The VRC 700 is designed to work with the more complex system. If you have multiple heating zones, underfloor heating or you use renewable technologies, the VRC 700 is the control for you. The control can decide on the most efficient heating appliances to run while also accounting for the weather outside and your energy tariffs. The VRC 700 works with all Vaillant heating appliances including boilers, heat pumps and solar thermal systems, as well as hybrid systems.


Commercial System Plate Heat Exchangers

Commercial System Plate Heat Exchangers are designed to separate the system water from the boiler. Fitting a plate heat exchanger is the ideal solution where it is difficult to guarantee system cleanliness and therefore water quality through the boiler. It is suitable for older applications where the systems cannot be pressurised. By separating the boiler from the system, the integrity of the boiler is maintained and it can operate as a pressurised system


Low Loss Header Vs Close Coupled Tees

Traditionally Close Coupled Tees (CCT’s) have be used in the Commercial Heating sector, they do work very well, But there is now a new trend of fitting low loss headers (LLH’s) instead of CCT’s. Let’s have a look at some facts about these Low Loss Headers, Close Coupled Tees and also Buffer Tanks. Any component, or combination of components, that has very low head loss, and is common to two or more hydronic circuits, can provide hydraulic separation between those circuits. A LLH reduces the flow
