Its been 3 years since my last topic here.
My dad's house with the frozen steam system we talked about 4 years ago was foreclosed and repurchased and I am watching as they remove all that cast iron. Curious as to what changes are being done.
My home I got advice on 3 years ago about various convectors for and landed on a CI rad/radiant mix system with CI boiler and indirect will be on the market this week, as we've built a new home! I will miss those 110 year old rads. What a great system it's been.
On to something new. Over the last year my fiance and I (yes, we're engaged now) have been working on our new home. I had selected a combi mod/con boiler this time around and having only ever installed CI boilers in the past am enjoying the current century's trend for a change.
Consulting various people in the business I was turned away from HTP unit and to an unfamiliar Bradford White Brute FT boiler, a FTCW199. The salesmen claims these are a very solid built machine with very few reported defects and the installers really enjoy working with them. I did my own due diligence on the unit and agreed, plus it is a great value with everything that is included and integrated.
I went with the combi for cost and space requirement reasons over using an indirect or standalone water heater. The new home has a small attached garage which would serve double purpose as the utility room. I had the foresight to install osb on the walls and have the contractor sheet rock over it, so I could mount/hang things virtually anywhere.
The unit many are unfamiliar with but has a 199k input with 10:1 turn down. It has an stainless tube heat exchanged with aluminum finned tubes. Included is ODR, pump delay features, venting kit, LP conversion, overall a very complete package. It uses a 15-78 internal pump and was definitely designed to be easily maintained with great access to components like the control board and igniter.
The home is well insulated and will be heated primarily with six 300' loops of in slab radiant. 2 zones, 2 loops for the garage and 4 for the house. A 1500 sqft footprint with 2 stories. Supplemental heat will be provided in areas upstairs and in the main living area by daikin heat pumps.
I spent the weekend doing the majority of the install myself with no other help or input, and just wanted to post a picture for any constructive feedback or considerations. I will be finishing it up this coming weekend just need to install the vent lines, end switch wire and pressure test.
