First Radiant Heating System Quote Came in Today

We received our first quote today from Steve Haldi at Hannel Steve quoted pretty much everything needed for a closed system using an electric water heater. The entire package came in at just under $2,500 and included the following items:

  • 1 – PaceMaker E3R electric water heater)
  • 1 Trim Kit
  • 2 Loop Supply and Return Manifold with PEX adapters
  • 1 Circ. Pump
  • 2 Extra PEX Repair Couplings
  • 1000′ 1/2″ “MR. PEX” Tubing
  • 1 Tubing Cutter
  • 1 Control Panel
  • T&P Valve and Drain Line
  • Tubing Layout if needed
  • Trim Kit – Manifold and Controls Assembled and Mounted, Pre-Wired, Pre-Plumbed
  • 1 Thermostat
  • 400 Ties
  • 4 Elbow
  • Closed System Kit
  • Pressure Testing Kit
  • Complete Instructions for Installation
  • Delivery with Lift gate is Included (within the contiguous U.S.) for complete packages.

That’s a lot of stuff for a small price in my opinion!

Now I would want to make this and open or indirect system in order to use the same water heater for both the domestic hot water and the radiant system. The kit to do this would run us an extra $800. I would also want to use an electric tankless water heater to improve efficiencies, reduce installation costs and save valuable square footage. I’m still not sure if a tankless unit will work in this application, especially if we intend to add a solar hot water supply in the future, but we’ll figure that out later. The unit I like the most is a Stiebel Eltron Tempra 20 unit that looks quite sexy and retails for about $500.

So we add $800 to the quote, subtract $600 for the water heater and add another $500 for the Tempra unit and we end up around $3,200 for the entire radiant heating system and our domestic hot water source! Not bad. Not bad at all. Let’s assume the house will be 1,100 square feet and that is a measly $2.90 psf for glorious radiant heating that will keep our feet toasty warm all winter long!

Let’s go back to the water heater for a second. I love the look of this Tempra unit. I see no reason why this unit could not be openly displayed in the home and eliminate the need for any utility closet whatsoever. That will save a good 3′ x 5′ of floor space minimum as well as the walls and doors that would have to accompany it. It could make a great discussion piece as well as visible advertisement for some of the green features of the home. See hypothetical conversation between homeowner and guest below.
