Condensing boiler temperature setting advice. condensing) when only a few rooms are heated.

• Condensing boiler temperature setting advice is there a valid concern at all by setting the boiler's CH temperature too low, even if it still manages to Hi, I recently called the BRITISH GAS energy helpline and asked what was the best way to run a COMBI-BOILER. Money and Energy Saving; Boiler Pressure; Boiler Service; Boiler Types; however for this technique we set the boiler flow temperature to 55 degrees, which virtually guarantees condensing efficiency savings. it’s important to note that there are many There are certain variables that determine the temperature at which homeowners should set their boilers, including personal preference and the weather. Sorry about the delay in replying. I have a Vaillant heat-only (conventional) condensing boiler. When the boiler water temp falls below 160, the circulator cycles off. 020 8682 2244. If your boiler was installed within the last 16 years, it’s most likely a condensing boiler. Thanks for all your continued help/advice guys appreciate it . Adjusting boiler temperatures correctly can The boiler needs to be set up with separate heating and hot water temperatures, a low efficient temperature for heating and a high safe temperature for hot water. Hot water cylinders need to be kept at 60 degrees - to avoid the dangers This has the potential to improve the boiler efficiency from around 78% efficient (non-condensing boilers) to 92-97% efficient for a condensing boiler. This isn't rocket science to adjust, and when you've figured out how to do it you can fine-tune it for maximum efficiency and comfort without paying for multiple visits from the tech.

Tags Navigation Bathrooms, Showers And Wet-rooms Water Underfloor Heating Green Energy Commercial / Industrial. 04 a year. If the boiler is operated in the real world, with a constant high temperature set By setting a maximum flow temperature that prevents the boiler from venturing into high-temperature, non-condensing ranges, the system can run more consistently in its most efficient mode. This setting keeps the boiler working at peak efficiency while ensuring your home stays toasty. When boilers are installed, they are usually set at between 70C and 80C, but this is hotter than it needs to be. A flow temperature of All modern, well-maintained boilers burn their fuel efficiently. Most condensing boilers are set up to supply one temperature for heating and hot water, in which case you should have it set to 70 degrees to be safe. Don’t set it any lower than this or the boiler won’t be able to heat your hot water cylinder to a safe temperature. For most condensing boilers a flow temperature of 70 C will give reasonable efficiency and good heat up times for the heating. Flow temp set to 60 since December Balancing does NOT increase condensing at the boiler contrary to popular belief. Moderately insulated but def some leaky spots 90s build with upgrades. Condensing boilers only really condense properly (thus extracting the waste heat from the flue gases) at a water return temperature of 54C to 56C. The system is an open vent. New boilers. In order to reach 92% efficiency however, the flow temperature for heating I have heard that reducing the temp on a non condensing boiler will not really save you much money . if, like most households, you have a modern condensing boiler (or even a heat pump), then it’s a different story. I've set my combi boiler flow temperature for central heating to 60 degrees (as per Martin's recent advice). How-to Older Baxi Solo condensing boiler - optimum temperature Country-specific Advice. but at condensing temperatures you'll have to time the The Vitodens 050-W gas condensing boiler is ideal for smaller homes and apartments due to its compact dimensions, low weight, and quiet operation. There are more choices than ever when it comes to heating, but most homes still use gas, oil or LPG. Fin tube doesn't really put out much heat under 120° supply. Most boilers in the UK are set at flow temperatures much higher than 60°C (often 70-80°C) A flow Baxi heating and hot water solutions - Find help and advice, FAQs, how-to guides, customer support contact details and more here Every condensing boiler has a pipe that transports waste water produced during the condensing process outside the property. Although this uses energy, The lowest temperature setting, 1, is typically set for a cool room temperature. A high flow temperature prevents Heating advice; Contact; Available in the UK. With a stat on the system, what level should the Our controls are just normal ones and boiler has tobe set manully. Assuming that you have a condensing boiler then the lower the return temperature below the dew point then the better it condenses & the more efficient it becomes (but we are talking a few % not massive amounts) so burns less gas for Condensing combi boilers often have their flow temperatures set between 70°C-80°C by default (flow temperatures are the temperature that a boiler heats water to before sending it through the radiators). Cover your external condensate pipe with foam pipe insulation. Condensing boilers achieve high efficiencies because they can recapture the latent energy from the moisture in the combustion gases when those gases condense. Condensing boiler with an indirect DHW system and outdoor reset control . For hot water, 60°C is the Condensing boiler temperature. A condensing boiler is a gas boiler . it may The higher this is set, the quicker the system will heat your home. 24c-AS/1, 28c-AS/1. However, many homes with condensing combi boilers can be suitably warmed with a heating flow temperature of 60-65°C or Advice. So, if you design a system for those temperatures and size the radiators accordingly, are you still expected to run the boiler at 80C? I suppose the clue is in the word "system", not "boiler". Leon82 Member. aeromech3 Senior Member Posts: 3598 Personally Autumn and Spring temperature set lower than Winter, and most my thermostats (15 in all counting the TRV's) are set as Boilers, like all things, are designed to be most efficient at 100% so turn the boiler temperature up to maximu, and then balance your system correctly to get the right flow through all the radiators and for a 55degree return temperature. TRVs on most rads The boiler has the normal flow temperature controls on the front for setting the main boiler running temperature But my question is, at what point does this good advice become bad advice? Why does reducing flow temperatures on condensing boilers make such a big difference? we recommend setting the flow temperature on your boiler to 55c for heating and hot water, and setting your hot water cylinder to 55c also (you’ll usually find the control for Boiler Settings. Essentially, it looks at the outside temperature, the call for heat, and the return temp (at least many do), and figures out if you could run the boiler temp lower. It is essential to match your boilers and appliances Turning boiler temperatures down does save money, with the Energy Saving Trust suggesting savings of anywhere between 9% and 13%. Mostly online info says boiler has max temp of 80 degree and keep it to 65 degreeto get best efficiency but our 0. They provide optimum comfort and are perfect for modernisations and new builds. For condensing to occur, the boiler’s heat exchanger surface temperature must be If you have a condensing combination (combi) boiler you can adjust the flow temperature. I appreciate the advice and suggestions. A I have 6 zones in a 2. Remember that you will have to set two distinct temperatures for the hot water tank and the central heating. If water temp is set at 150° and if 70% keeps that temp it won't run at 100%. However, having read your post, the installer had set the boiler temp at about 80C, so I've turned it down to about 70C to see what happens! Hot water Try turning the boiler’s flow temperature down to 65 degrees. then the boiler will default to the HW set temperature until the HW zone valve closes.
