Any plumber will tell you that it’s not an easy task to control the temperature of a solid fuel stove that’s supposed to work with your heating system. A Gas or Oil boiler has its own stat controls to regulate whatever temperature you desire… but you can’t do that with a Solid fuel Stove as it depends on how much fuel you put into it. But there actually is a way that you can get full control over your solid fuel stove with Oxyvent.
How do Solid Fuel Heating Systems work?
Most Solid Fuel heating systems work by firstly heating up the water inside the stoves boiler to 65°C and then pumping this hot water through your heating system and radiators. But as that happens, cold water from the radiators is introduced to the bottom of the stove boiler. When this cold water hits the hot surface inside the stove, it causes a serious reaction called “Thermal Shock”, which is the banging, rattling noise you always hear. As well as making noise, Thermal Shock also affects the flame of the fire, making it difficult to control the damper setting and maintain the output of the stove. This significantly reduces its efficiency, resulting in poor heat from your radiators and a waste of fuel.
The Oxyvent way
Oxyvent uses two separate temperature controllers and two pumps to regulate the water temperature within the Stove. One controller regulates the water leaving the stove, set at 60°C, whilst the other regulates the water coming back to the Stove, which is set at 50°C. Once the fire has heated up the water, the first pump moves the hot water out of the stove, through the Oxyvent Tank and back to the stove’s boiler. When the water returning to the boiler reaches 50°C, a second pump moves the water through the radiators.
The cold water from the radiators then goes through the unique patented design of the Oxyvent Tank, which increases the water temperature to 50oC before it can enter the stove. This prevents any thermal shock from occurring and prolongs the life of your stove.
The 2 temperature controllers maintain a balanced water temperature within the stove of between 50°C and 60°C at all time. We have found that when you balance the temperature of the water entering and exiting the stove to within 10°C like Oxyvent does, the benefits are enormous – including a much more efficient stove, more heat getting to your radiators and superior control over the damper, allowing you to regulate the flame of the fire much better.
Oxyvent Boiler protection
Oxyvent has the only system that goes beyond manufactures guidelines on keeping the return water temperature above 45°C which also prevents condensation in the stove. Since the cooler water returning from the radiators is not allowed back into the stove until it has reached 50°C, it completely eliminates any condensation problems within the stove. Oxyvent has achieved this electronically with its uniquely designed wiring system with built-in boiler protection for your stove.
New Oxyvent Wiring Board
Oxyvent has designed a unique wiring board specifically suited to solid fuel system.
• Unique safety feature that automatically over rides room stats while solid fuel is operating
• Separate connections for each component for easy tractability
• Light come on for the zone that is operating
• 3 Heating zones and hot water zone
If you are experiencing any issues with your stove, then you need an Oxyvent System.
Frequently asked questions on Solid Fuel Stoves
This is very common complaint when it comes to zoning solid fuel with oil or gas. With the existing system the plumber is given it is not possible to zone a house properly. The Oxyvent system is designed specifically for zoning solid fuel with oil or gas. Our unique wiring system will give you the choice of zones with the Oil and a separate choice of zones for the solid fuel. With unique built it safety features.
There are several reasons why this happens, poor circulating, incorrectly piped, sludge in the system etc. This is just an indication that the system is not function correctly. To solve issues like these in solid fuel systems it is all about temperature control. Oxyvent is the leader when it comes to controlling water temperatures in solid fuel appliances.
Two reasons why this happens. It is either water trapped inside the stove that cannot get out or the most common reason is thermal shock. Thermal shock occurs when hot and cold water collide inside the stove. As the existing system has only one pipe stat (temperature control) to regulate the stove temperature, then thermal shock is inevitable. Oxyvent use two temperature controls which eliminating thermal shock.
For the first time underfloor heating can be operated with solid fuel on an open vented system. This means there is very little pressure in the system as it is operated off the tank in the attic. Less pressure on pipework and less chance of leaks. Solid fuel is very effective and efficient at the lower temperatures underfloor heating operates at. No plate heat exchangers used. No pressurizing the system. Less maintenance.
Only with Oxyvent can it operate efficiently. The temperature regulators and independent circuits for each heat source will lead to a smooth transition to a flawless system. The oil boiler will switch off once it has reached its 60°C setting. The stove will then take over to heat the radiators. Once the output of the stove is kept up the Oil boiler will not switch back on. It is only when the temperature in the stove drops that the oil boiler cuts back in. There will be no banging or gushing water noises. The high limit stat on the boiler will not lock out due to overheating, like what happens with the existing system.
What our customers have to say
We answer your questions
How often were you given the same suggestions to fix radiators in rooms that don’t heat: Check for air in the system, Fit a larger pump, Check the water pressure, Check if the radiator valves are stuck, etc etc
Where Underfloor Heating is installed with a gas or oil boiler, hot and cold patches on the floor are quite common. It can get very uncomfortable when the floor overheats. What can we do about it?
People normally place their hand on the top section of the radiator to find out if their heating is operating properly. This is not the correct way to find out if your radiators are functioning efficiently.
