Snowmelt w/takagi/glycol questions
Hello all. i recently purchased a house w a glycol filled takagi tk1s fired boiler snowmelt system .i just need some help...i know the system may not be to eveyones liking but its there so i will use it,,,i was wondering how many gpm is needed w system, i think the boiler has a 7.5gpm max. it has a taco 009 pump. the system is feeding 6 zones ,4 of the zones are approx 300 ft each of 5/8inch pex in concrete under pavers,the other 2 zones are 1/2 pex under steps and small walk way, the driveway is apprx 800sq ft..i recently flushed it all out and installed new gylcol. i have the re-02 remote on takagi and it is show the system flowing 2.1 gpm..that seems low, was thinking of going with a 0013 pump to try to get up to 5-6 gpm....any feed back would be great... thanks Reply Edit
