]]> Comment on Correct capacity is key to biomass heating success by Gavin Gulliver-Goodall http://www.enagri.info/blog/?p=461&cpage=1#comment-160 Gavin Gulliver-Goodall Wed, 16 May 2012 19:53:51 +0000 http://www.enagri.info/blog/?p=461#comment-160 Hi Richard two thoughts a wanted to share: re hotel, I think I know the project and if its the one I think then the client detemined the boiler rating and connectoin. 2 x bags of pellets per day is about right for a 25kW nominal boiler its doing what its abel to do. ofcourse that you have to carry 2 bags every day through the house is the key flaw to the stove-boiler product. although most seem to suffer from being too fragile to last a Uk winter or two. the key thought is that the client wont buy from you if you tell him he is wrong. on the bigger boiler, as we have discussed on other forums: the succesful biomass installtion relies on many aspects being correct. key are: boiler to match avaiable fuel, fuel store being correctly sized adn positined to accept economic deliveries. fuel store being adequate to handle the fuel and deliver to the boiler, buffer sized so that boiler does not cycle excessively. boiler and buffer and heating controls integrated so that cycling does not occur dueto hihg return temperature. flue correctly sized adn installed to remove combustion products safely and not produce incorrect draft on the boiler. boiler positioned to allow proper maintenance in commercial jobs, heating controls (BMS) correctly programmed to meet design requirements. heat users educated onwhat to expect form heating. boier opeator educated on how to service and maintain boiler. if any one of these is not optimal then the system will not work and the boier (usually) is blamed. what has this to do with oversized boiler? a correctly instllalled boiler with correctly sized buffer and controls doesnt mind being over sized it just runs less and has cost more to put in. as a real boier installer with a tied product range I select teh boeir with the best fit to the cleints needs from what I have available. which means a 100kW boiler for a 65kW nominal load. in rhi terms this may give the client more income opportunity if they use more heat. it may cost more than competitors products ( different size or otherwise) but clients buy form me becasue i do it right and support the install never because i am cheapest becasue i never will be. OTOH i suspect my still working and in use after 3 years percentage is a lot higher than the national average alas I have lost contact with some old customers .With the RHI there are also lots of undersized boilers going in at the 200kW cut off. so swings and roundabouts. Hi Richard two thoughts a wanted to share:
re hotel, I think I know the project and if its the one I think then the client detemined the boiler rating and connectoin. 2 x bags of pellets per day is about right for a 25kW nominal boiler its doing what its abel to do. ofcourse that you have to carry 2 bags every day through the house is the key flaw to the stove-boiler product. although most seem to suffer from being too fragile to last a Uk winter or two.
the key thought is that the client wont buy from you if you tell him he is wrong.

on the bigger boiler, as we have discussed on other forums: the succesful biomass installtion relies on many aspects being correct. key are: boiler to match avaiable fuel, fuel store being correctly sized adn positined to accept economic deliveries. fuel store being adequate to handle the fuel and deliver to the boiler, buffer sized so that boiler does not cycle excessively. boiler and buffer and heating controls integrated so that cycling does not occur dueto hihg return temperature. flue correctly sized adn installed to remove combustion products safely and not produce incorrect draft on the boiler. boiler positioned to allow proper maintenance in commercial jobs, heating controls (BMS) correctly programmed to meet design requirements. heat users educated onwhat to expect form heating. boier opeator educated on how to service and maintain boiler. if any one of these is not optimal then the system will not work and the boier (usually) is blamed.
what has this to do with oversized boiler? a correctly instllalled boiler with correctly sized buffer and controls doesnt mind being over sized it just runs less and has cost more to put in.
as a real boier installer with a tied product range I select teh boeir with the best fit to the cleints needs from what I have available. which means a 100kW boiler for a 65kW nominal load. in rhi terms this may give the client more income opportunity if they use more heat. it may cost more than competitors products ( different size or otherwise) but clients buy form me becasue i do it right and support the install never because i am cheapest becasue i never will be.

The wood panel and furniture industry exploit UK timber growers, turning to imported supplies the instant prices rise. We welcome markets for the worst quality timber, which would otherwise be unlikely to be harvested, for offcuts and by products from sawmilling and processing, and for lop and top. The RHI is at last bringing England's woodlands back into production after many years of decline: a decline that has affected biodiversity as well as incomes. We are now reversing these trends.

This should make it abundantly obvious that the power will be sent ELSEwhere those ll5k.v. (soon to be 230k.v.!!) powerlines don't exactly hook up directly to Gretna City Hall!

Much of the opposition seems poorly informed and expecting environmentalists such as myself to have a knee-jerk reaction against this project without providing a more detailed description of the technology proposed.Thank you,Mark E.
