May 23, 2018 · Any zones are shorter than 50' (10,000 BTU/hr out at condensing temperatures) are a real short cycling problem for a boiler that can only dial back to 14,000 BTU/hr out. The 16 gallon tank is only storing domestic hot water as a small indirect-fired tank, which is fine, but it's not a heating system buffer that would help suppress short cycling.Get Price
Mar 04, 2016 · With 180' of baseboard and a load of 40,000 BTU/hr the baseboard only needs to emit (40K/180'=) 222 BTU/hr per foot, which can be delivered at an AWT of about 125F, which means it would be a good candidate for a small condensing boiler, and it also means your distribution losses would be less than half that of running the system at an AWT of 190F.Get Price

In relating boiler input to gas rate, manufacturers use different values for the calorific value of the gas. 10.5 is a popular figure (you'll find a range of 10.4 to 10.6 used for different power versions of the same boiler), 10.75 another. That range is enough to turn a boiler that's burning 2% above nominal rate into an apparent 5.5%.Get Price
Jul 01, 2015 · I'm currently looking to upgrade my old boiler as it developed a small crack and is leaking.

Sep 25, 2014 · Not a bad guess ; according to the manual, the smallest is 11.7kW. It also (page 12 para 3.2) gives the water resistance for an 11C temperature rise. So we can safely assume the boiler is designed for an 11C rise. The flow rate will therefore be: 11.7 / (4.18 x 11) = 0.254 litres/sec = 0.92m³/hr.Get Price

Jan 03, 2020 · >"I think #11 is most representative of a condensing boiler with indirect DHW tank." Look at Appendix 11- that's a LUDICROUSLY oversized 160,000 BTU/hr mod-con, probably with no more than a 5:1 turn down ratio. Even so it would still beat most standalone tank water heaters, but probably not a condensing tank water heater.Get Price
The efficiency of the boiler does not really change wih modulation. In a condensing boiler, it changes with return temps. So during the shoulder season, I expect higher efficiency than during the design days. It's the opposite of a cast iron boiler! As for 2 boilers to get 50-80 MBH, that seems way too complex.Get Price
Dec 18, 2019 · The smallest HTP wall hung combi has a minimum-modulation rate of about 14,000 BTU/hr-in, which at condensing efficiency would be about 13-13,500 BTU/hr out, not less.

Usually boilers with less than 500,000 BTU/Hr. output will come pre-assembled, while larger boilers will come unassembled.
