Closed circuit
With a closed expansion vessel there are no water or air losses, corrosion is limited and pressure and temperature stay steady. Safety valves prevent overpressure. The closed circuit kit is for this circuit.

Description
A kit for every way of connecting.
Werstahl connection kits contain the main parts needed to connect a water-heating fireplace to the radiators of the house. There are three, one for each way of connecting: for an open circuit, for a closed circuit and with a heat exchanger.
All three have an inverter circulator, a T90 temperature and pressure relief valve against overheating (3 bar or 94°C) and an electronic thermostat that shows the water temperature and switches the circulator on and off. The open and closed circuit kits also have a three-way motorised valve, and the closed circuit kit adds a 3 bar safety valve. The heat exchanger kit has two circulators and a Swep plate heat exchanger with 30 plates.
The kits come with a detailed connection diagram drawn up by a mechanical engineer.

Highlights
Open, closed or with a heat exchanger?
The three ways of connecting, as Werstahl describes them, with its diagrams.
Open circuit
The water is in contact with the air and the pressure stays close to atmospheric. It is simple and cheaper to install, but it loses water to evaporation and needs more frequent servicing and topping up. The open circuit kit is for this circuit.
With a heat exchanger
The fireplace runs with an open expansion vessel and the radiators on a closed circuit. The heat exchanger separates the two circuits: less corrosion and steady pressure on the closed side, and protection from overheating. The heat exchanger kit is for this circuit.

Questions
Ask us before you buy.
Our technicians answer every question, from choosing to installing.
2610 334 389 info@climaventis.grWhich kit do I need?
It depends on how the fireplace is connected: with a closed expansion vessel the closed circuit kit, with an open vessel the open circuit kit, and with the fireplace on an open circuit and the radiators on a closed one the heat exchanger kit. Our mechanical engineers will help you choose.
Which fireplaces are they for?
For Werstahl water-heating fireplaces. Ask us about your fireplace and installation.
What does each kit contain?
Open circuit: an inverter circulator, a three-way motorised valve, a T90 relief valve and an electronic thermostat. Closed circuit: the same plus a 3 bar safety valve. Heat exchanger: two inverter circulators, a Swep plate heat exchanger with 30 plates, a T90 valve and a thermostat.
Which circulator do they have?
An inverter circulator (two in the heat exchanger kit), chosen to suit your installation. Tell us about your fireplace and your home.
What does the thermostat do?
It shows the water temperature and switches the circulator on and off.
What is the T90 valve?
A temperature and pressure relief valve against overheating, for 3 bar or 94°C. All three kits have one.
Does it come with a connection diagram?
Yes. The kits come with a detailed connection diagram drawn up by a mechanical engineer. A plumber makes the connection.
How is it delivered?
The kit ships by courier throughout Greece, with the cost shown in the cart, or you collect it from our shop in Patras.
