How efficient is my Potterton Suprima boiler?

How efficient is my Potterton Suprima boiler?

The Potterton Myson Suprima 50 has a SAP seasonal efficiency rating of 77.5%. The Suprima 50 is a Non-Condensing Conventional boiler with a maximum power output of 14.7kw that uses Gas as its fuel source.

Why does my boiler keep firing up?

It could be a component, such as the heat exchanger or an internal thermostat, in which case you should not attempt to fix it – call a gas engineer who will be able to assess the situation and recommend a repair or replacement. Making sure your boiler has its annual service should prevent this stop-start pattern.

How do you fix a short cycle on a boiler?

Adding thermal mass to the heating system will decrease the burner short cycling and this can be done by adding water volume to the system. A relatively easy way to add thermal mass is adding a “Buffer Tank”. A “Buffer Tank” is simply a tank of water. For buffer tanks, one size does not fit all applications.

Why does my boiler keep cutting in and out?

If the boiler keeps shutting off, it could be due to closed valves, air caught in the system or a broken pump. The boiler is switching itself off due to in-built safety mechanisms – if it did not shut down, then the boiler could overheat. A closed valve can also prevent water from flowing properly within the boiler.

How efficient is my old boiler?

However as the vast majority of condensing are still set up to run like a non-condensing boiler, so the efficiency is in line with old style boilers, as follows: Over 25 years old: 60-70% efficient. 20 years old: 75% efficient. 15 years old 80-85% efficient.

How efficient is a new gas boiler?

A-rated boilers are more than 90% efficient while G-rated boilers are usually 65% efficient, highlighting the gulf in performance between an older boiler and a modern one. As of October 2010, newly installed home units have to be 88% efficient or more. Efficiency is also based on the type of model you have installed.

Is a short cycling boiler dangerous?

If your furnace is on and off repeatedly, this is known as short cycling, and it’s very dangerous. A unit that turns on and off, generating heat then shutting down, over and over again, may break down quickly. It may also need frequent repairs and could even have a decreased life span.

Is it normal for boiler to turn on and off?

If you have a combi boiler and it turns itself off every now and then, it’s probably the boilers ‘pre-heat’ function. This is perfectly normal and doesn’t indicate a fault with your boiler, your boiler is just turning itself on to pre-heat water so that it’s ready on demand when you need it.

Are there any problems with the Potterton Suprima?

They came in many heat output sizes from 30,000 BTUs right up to 120000 BTUs and all in the same size case. The 120s were recalled a few times due to problems and eventually withdrawn, but all in all, they were a good boiler. The Potterton suprima had its faults though and one of them was the PCB or otherwise known as the printed circuit board.

Is the Potterton Suprima boiler still a good boiler?

This used to make the boiler go into lockout. Everything needed comes in the box. All in all the Potterton suprima was and still is a good boiler compared to today’s condensing boiler. Potterton suprima were a very good boiler in their time, they were small and compact and would fit nicely inside a kitchen cupboard.

What does flashing red mean on Potterton Suprima boiler?

I can’t remember now.) The Potterton Suprima Replacement PCB Kit manual says that flashing red 3 times/sec indicates an air pressure switch (APS) fault or a flow switch fault. We opened the boiler up to check if a flow switch was fitted (sometimes called a dry fire switch) but there was none on this boiler.

Are there any problems with the Potterton 120?

The 120s were recalled a few times due to problems and eventually withdrawn, but all in all, they were a good boiler. The Potterton suprima had its faults though and one of them was the PCB or otherwise known as the printed circuit board.

Why did Potterton Suprima boiler shut down after 15 minutes?

Potterton Suprima boiler shuts down after 15 minutes, then “dead” for hours with no lights before working again We’ve added this fault because the way it presented was unusual. Our customer reported that the boiler would fire normally in the morning for about 15 minutes before shutting down.

When did the Potterton Suprima circuit board come out?

The data plate carried a “00” year code indicating it was manufactured in 2000. We removed the screw which allows the control panel to flip down and inspected the board, finding the classical darkened scorch mark which is typical of Potterton Suprima circuit boards of this type.

What does red ignition lead mean on Potterton Suprima boiler?

This lights the burner. The red ignition lead serves a second purpose. When the burner has lit, and only when it has lit, a small low voltage flame rectification current passes along the lead and is sensed by the circuit board. This current indicates the presence of a flame and the circuit board allows gas to continue to pass from the gas valve.

What causes a lockout on a Suprima gas boiler?

This indicated an alternative likely cause for the lockout, a failing ignition lead. We looked to see which type of ignition lead this boiler carried. The early leads were composed of a graphite core formed round glass fibre thread and covered with a red, rubberised insulation. These are the Suprima ignition leads which give lockout problems.
