DS-3 – Buffer Thermal Store, Cylinder with Hot Water Plate Heat Exchanger – 220-500ltr

From: £975.00



This system is designed to work in conjunction with a wood pellet boiler. The system includes a plate heat exchanger assembly to generate mains pressure hot water, fitted with thermostatic mixing valve to control output temperatures.

A circulation pump and loading valve must be fitted as close as possible to the wood pellet boiler, inline with manufacturers recommendations. Contact Thermal Integration for prices.It is assumed that the system will be pressurised and as such the store is fitted with a pressure and temperature relief valve.

It is also assumed that expansion relief is provided by the pressure relief valve fitted within the pellet boiler, the filling loop is fitted separately (or in the boiler), and an additional expansion vessel may be required to cope with total system volume.
