New Boiler install with...
Am replacing my 29 year old Burnham RS-112 (125k rated) steel dry base tweaked down to .75/80B with a tankless coil. Cracked fire box and age is the reason. Although still dry as a bone. Am using the L7224U- 1002 Aquastat which I plan on using on my new Burnham RSA - 125 (125K rated) nozzled down again to .75/80B again with a 5 gpm tankless. The new boiler has a Beckett Genesis 7505B 1500 control and my question is - is it worth the expense for either the Beckett Heat Manager or the new AquaSmart control to automatically do what I have been doing for years. And that is with the 7224 I set my HL to 185 with a HDF at 20 - my LL at 155 with a LDF at 20 in the cold season. Then the HL at 160 with a HDF at 20 and a LL at 145 with a LDF at 10 during the warmer seasons. I am heating an 1800 sq.ft. Cape that could use some more insulation in attic areas where I can get to and I use an average of 650 gals. per year. Don't know if just the fact that the unit will be new and doing what I have been doing will save me some gls/year ( I do keep the unit very clean and tuned more than the norm.) or if it's worth changing to either of the products I mentioned. Also one last question is my L7224U is Enviracom compatible - what excactly is this and will this also make the new boiler more efficient? Thanks to al who respond.
