The pipe stat is wired into the CH zone valve by-passing the room stat. By doing it this way you only bring the boiler on to take the chill off it and the system to prevent potential freezing. Without the pipe stat the frost stat will keep cycling the boiler until the temperature around the stat creeps above its set point.
What should the pipe Stat be set to?
Is the pipe stat fitted on the flow or return, if on return all the rads will heat up until return water reaches set temp. Pipe stat should be set to 10, you only want it to stop the pipes freezing.
What is the point of the extra pipe Stat on boiler?
Pipe stat should be on the boiler return. It is wired in series with a frost stat. It is usually set to around 40deg. Its purpose is to prevent the waste of energy.
What does the Frost Stat do on a boiler?
The frost stat closes as the temperature in the loft falls; the pipe stat opens as the temperature rises. These two stats are wired in series, so they will only light the boiler if the air temperature is below the frost stat setting and the water temp in the pipe is below the setting on the pipe stat.
Why do I need 2 pipe stats on solid fuel?
normally 2 pipe stats are used on solid fuel, one to bring the pump on when the temp gets very high to help avoid overheating, the other to stop the pump coming on before the primary water has reached a good temp. If the pump kicks in when the primary temps are low you can cause thermal shock which can lead to heavy corrosion in the heat exchanger.
What should a pipe Stat be set at?
The frost stat should be set to 5 degrees, then a pipe stat ( L641B1004) is wired in series to the frost stat and normally set to 25 degrees this in turn all converges at the heating control wiring junction box for which the boiler is and other heating controls are also wired to.
What is a stat pipe?
A pipe thermostat is a mechanical/electronic piece of hardware that helps to monitor parts of a heating or cooling system, usually by attaching to a piece of pipe, and monitoring the temperature of the local area. A thermostat is a device that regulates temperature for a system.
Where do you put a pipe stat?
The Pipe Thermostats are attached to the gravity flow and gravity return pipes using the spring clips provided. They will generally be attached to the pipes as near to the boiler as is practically possible, but may be fitted to the pipes in the airing cupboard.
What does a low limit pipe stat do?
Low limit pipe stat. The L641 is a surface contact thermostat designed to sense the water temperature in storage cylinders and water pipes, and to provide temperature control, temperature limiting, and temperature feedback functions.
How does frost stat work?
A frost thermostat is used to protect your property from damage by freezing. It works by turning on your heating system if the temperature drops below the temperature you have set on the frost thermostat, allowing the user peace of mind.
What temperature is frost setting?
The frost protection setting turns your boiler on when it senses that the water in the system has dropped below a specific temperature. This temperature is usually around five degrees, and you wouldn't necessarily want it any lower than this, as the water could freeze before the boiler has a chance to warm up.
What temperature should pipe thermostat be?
The cylinder thermostat will have a temperature scale marked on it, and it should be set at between 60ºC and 65ºC, then left to do its job.

What is a Honeywell frost stat?
Honeywell Frost Stat T4360A1009 The T4360 is a mains voltage Honeywell Frost Thermostat designed to give automatic frost protection to boilers and pipework, as well as the fabric of the building. The thermostat should be fitted in the coldest areas e.g. loft space, floor voids, garages etc.
Where is the frost stat on a pipe?
The frost stat is on the outside of the pipe and the pipe stat is inside the pipe ?
Why do you need a froststat on a boiler?
If the boiler and or pipework is in a remote (cold, outdoor) location, then a froststat should be placed in this area, to prevent overheating of the building a pipestat may be installed on the return to the boiler. The pipestat should be wired in series with the frost stat.
Can a pipestat monitor water temperature?
yeah, it would do both, but if the boiler was in an draughty outbuilding then heat generated would take ages to 'warm up' froststat, thats why pipestats are installed to monitor water temperature
