Everything in the system is made of materials that are fit to drink from, and a plumbing detail prevents stagnation of the water in heat tubes during the summer when space heating is not required. For details of this system, see Open Direct System or see page 23 of the Installation Manual. By reason of its efficiency, cost, and simplicity, this is our preferred system.<\/p><\/blockquote>\n<p>While we have the ceilings open, we can install the PEX tubing and insulation under the floors. \u00a0We can also replace our galvanized piping in the basement as we reroute everything for the new system. \u00a0By removing the old water heater and furnace with a single small wall mounted heater, we clear tons of floor space. \u00a0We will not need ducting nor a chimney either. \u00a0Heat is delivered in runs of 5\/8&#8243; PEX tubing and exhaust can vent through the wall via PVC pipe. \u00a0With all this new found room in the basement I might have room for my <a title=\"secret laboratory\" href=\"http:\/\/www.saverpit.com\/movies_tv_1\/dexscreenshot.jpg\" target=\"_blank\">secret laboratory<\/a>!<\/p>\n<p>I recommend reading through the <a title=\"Radiantec\" href=\"http:\/\/www.radiantec.com\">Radiantec<\/a> website for more info. \u00a0It has a ton of articles about how this system works, potability, stagnation prevention, code compliance, and cost.<\/p>\n<div id=\"attachment_54\" style=\"width: 707px\" class=\"wp-caption aligncenter\"><a

Radiantec was to get them to spec out what we would need for our particular house. \u00a0With under 1000 sq ft of heated space, heat requirements were low enough to\u00a0substitute\u00a0a cheaper Noritz [<a title=\"NRC98-DV-NG\" href=\"http:\/\/www.noritz.com\/residential-products\/new-nrc98-series-condensing-tankless-water-heater\/\" target=\"_blank\">NV98-CV-NG<\/a>] tankless condensing gas water heater rather than the more expensive Polaris and a MUCH more expensive boiler. \u00a0This not only saves us money, but saves us floor space in our already tiny house. \u00a0At 92% efficiency, I hope it will also keep our heating and hot water costs low. \u00a0If not, we should be able to add solar water heating down the road.<\/p>\n<p>While we went with their whole system for heating, we opted out of the thermostats supplied by Radiantec (for now) while I explore using an <a title=\"Arduino\" href=\"http:\/\/www.arduino.cc\/\" target=\"_blank\">Arduino<\/a> micro controller to control our heating and eventual air-conditioning systems. \u00a0This is really nerdy stuff, but I&#8217;ve been waiting for a system control project to come up where I could play with it. \u00a0I&#8217;ve ordered an Arduino Uno, Ethernet Shield, 10x\u00a0DS18B20 temperature sensors, and an 8 channel solid state relay board (2A @ 120V \/ channel). \u00a0The plan is to build a system that we can access by apps on our phones, or via a website that can also datalog our energy usage. \u00a0If this doesn&#8217;t work, I eat the cost and we buy the Radiantec controls. \u00a0I&#8217;m sure there is <a

work.<\/p>\n<p>We&#8217;re so excited to start installing this stuff over the next few weeks. \u00a0Really looking forward to warm toasty bare feet this winter too.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>This has been an expensive week, but in a good way. \u00a0We&#8217;ve ordered and received our radiant floor heating system.
