The LK load units are built in Sweden to a very high specification and are designed to provide long term use and give accurate control of the water flow from a boiler stove. They are the unit of choice by most of our installers these days as they're so well made, so reliable and yet priced really well. The full unit, comprising the valve, pump, thermosyphon by-pass and gauges, comes as a neat and compact unit complete with insulating cover.
The purpose of a load valve is to make sure that the best possible temperature stratification in the thermal store is achieved and also a high temperature which returns to the boiler stove. This means that there is an increased life of the boiler stove and greater efficiency to the heating system.
The Laddomat 21 is a heat charger suited to boilers of up to 80kW output.
Esbe VTC load valves are 3-way thermostatic valves which can be used in conjunction with a pump and flue thermostat to maintain high return temperatures to the boiler.
The valves, pump, thermostatic gauges and thermosyphon bypass are all neatly contained, and the load unit comes with a removable insulating cover.
