Jaspi GTV 700 Thermal Store


GTV was originally developed as a buffer tank for wood and pellet boilers. Due to the arrival of the heat pump technology and increasingly popular solar heating, it has been upgraded with more external connections and the GTV700 has upper and lower tank thermometers for easy temperature monitoring.

Often when space is limited, GTV tanks are connected in a series only one of which have hot water and solar coils. This way the system can have more volume than one tank alone and the positioning is more flexible.

By linking tanks together it is easy to upgrade the thermal storage system when more volume is needed or the dwelling is extended.

GTV 700 can have up to three coils for heating, hot water or solar use.

All the models can be equipped with back-up immersion heater(s) from 3 to 6kW.
