Detailed Information

Description

LK 810 ThermoMat 2.0 is a loading unit for heating ­applications with solid fuel boilers and storage tanks. The ­loading unit is intended to ensure a high return temperature as well as an optimal temperature stratification in the storage tank, thus increasing the efficiency of the system. Tarring and ­condensation are prevented which prolongs boiler life.

The LK 810 ThermoMat 2.0 is a compact design with an integrated low-energy circulating pump and a thermic loading valve that regulates on two ports. The loading unit has three ball valves to simplify installation and maintenance, three thermo­meters that allow for simple control of the loading process and an ­insulation to minimize heat loss. The loading unit is ­available in two versions - with or without check valve. With a check valve the functions described under phase 4 will be ­obtained. The loading unit is reversible and can easily be adapted for mounting to the right or left of the boiler. Thanks to the three ball valves any part can be changed without draining the system in case of servicing.

LK 810 ThermoMat 2.0 is also available with a circulating pump that is controlled by a PWM-signal. For more information please contact our sales department.

LK 810 ThermoMat 2.0 is installed in the return circuit between the solid fuel boiler and the storage tank. The unit should be mounted upright with the drive-shaft of the circulating pump in a horizontal position.

The loading unit normally requires no maintenance. The installation should be checked regularly.

Application

The function of the loading unit during the different phases of heating:

1. Heat up phase

The water circulates between boiler and loading unit while the temperature of the boiler is rising.

2. Loading phase

The thermostatic element starts to open and allows return water from the storage tank to be mixed with supply water before it returns to the boiler. The return temperature to the boiler is kept constant.

3. End phase

The thermostatic element is fully open and the bypass is closed. This results in an optimal transfer of heat from the boiler and the storage tank is filled with supply water.

Self-circulation with check valve

Self-circulation will be obtained as soon as the fire has gone out and the circulating pump has stopped. The remaining hot water is loaded to the storage tank. In case of power failure or pump breakdown the check valve automatically opens to allow self-circulation. The check valve also stops recirculation from storage tank to boiler.

Questions & Answers

Do all LK 810 ThermoMat spare parts fit the entire range?

No, they do not. You can find the correct spare part in our Spare Parts and Accessories brochure, which you can find under Support/Brochures on our website.

 

Why can’t I find the right spare part (sensor body) for my loading unit?

Probably because you have an older product manufactured before 2010 under the name Acaso. The Acaso loading unit always stated the opening temperature, while on current loading units we always state the return temperature. You should therefore check the attached conversion table to find the correct spare part. You can find further information in our Spare Parts and Accessories brochure on page 21, which you can find under Support/Brochures at lkarmatur.se.
