Geothermal Radiant Heat & Cooling

Friday, June 9th, 2017

This system is 20 tons of cooling on a 10,000 sq ft home. We used Tekmar Controls to make it all work together, the main control is the Tekmar 406 house control. The 406 controls the Tetco heat pumps in a lead/lag configuration. The first stage is 2-5 ton heat pumps and the second stage is the other 2 5 ton heat pumps. There are 11 zones in the home, the Tekmar 557 touch screen thermostats control each zone of radiant heat/cool and forced air hydronic air handlers. The thermostats monitor the humidity and dew point and then reset the water temperature that goes out into the floor, avoiding condensation collecting on the floor during cooling. This system also has a 8 panel Solar Panels Plus evacuated tube solar collector system with a 500 gallon drain back tank. The tank provides domestic hot water and injection into the radiant floor during Heating.

Heating Season 2014-2015

Friday, September 12th, 2014

We are now entering the 2014 heating season. Now is a good time to have a annual checkup on the appliance that provides you comfort during the cold winter months. Annual checkups help to find problems that may not show up until the appliance gets a good workout on a cold winter day. Many times HVAC equipment will break down during a long cold spell and when that happens, most of us HVAC contractors will be booked solid fixing and repairing these systems.

Some key components of a typical tune up include:

  • Filters (I recommend monthly replacement/cleaning)
  • Sources of carbon monoxide (leaky heat exchangers)
  • Strange noises (fan motor bearings failing)
  • Gas burner adjustment (spiders can build webs, causing poor combustion)
  • Flame ignition systems (Hot surface igniter can be cracked)
  • Pressure switch malfunction (causes lockout of equipment)

We can provide the following services:

  • Combustion analysis (set burner for proper combustion) This will identify problems not seen by visual inspection. Combustion analysis is  performed using a computerized combustion analysis  tool. Our tool is sent to the factory yearly for calibration.
  • Heat exchanger test ( test for leaky heat exchanger in furnaces)
  • Carbon Monoxide Test (CO2 test each room)
  • Load calculations (We can run a load calculation to determine proper HVAC equipment sizing)
  • Cleaning Blower Fans ( Dirty fans wheels do not provide the proper air flow to the heated space)

Boiler maintenance:

  • Check proper flow through the hydronic circuit
  • Check Pumps/circulator
  • Check Flue Draft
  • Boiler Control and Outdoor Reset Function
  • Mod/Con High efficiency Boiler Setup and Diagnosis
  •  Modulating Condensing Boilers need annual service to provide the highest possible performance they are capable of. Annual combustion analysis and cleaning are very important!!
  • Feed valves and Glycol feeders need to be checked for proper operation.

Nuvo H2O water softener

Friday, November 23rd, 2012

My people don’t like showering with soft water because it tends to have a slimy feeling on the skin, it feels like you can’t get the soap off.
If you are one of these people that don’t like that feeling then the Nuvo H2O salt free water softener is for you. Nuvo uses a citric acid cartridge element that releases citric acid, which binds with hard water molecules. This makes the hard water molecules unable to attach to surfaces, fixtures and plumbing pipes. Citric acid is non toxic and can be used in the potable plumbing system, it also tastes great.

Solar Thermal Collectors

Sunday, March 16th, 2008


Solar Thermal Collectors are used to capture radiation (heat) from the sun. The sun’s energy that reaches the Earth on a daily basis, has enough energy to power the World for a year. Why not capture a small portion of this heat, and use it to power your home, heat your water, heat your home, or heat your swimming pool? Solar Thermal systems are cost effective, and the Government will give you a Tax Credit for installing a system. This will help offset the cost of the system, and help with the return on your investment.

Why Use ICF Construction for your New Home

Monday, April 11th, 2005

ICF (insulating concrete forms) is a particular form that you stack and link together to form a wall, within this wall there is rebar, and concrete. The outside of the form is usually Stytofoam. There are tabs usually every 8 inches that the drywall can be screwed to, and also vinyl siding and stucco lath.
The concrete in these forms is very strong, because of the slow cure time, around 90,000 psi at the peak cure. So we have a Toronado proof, wind proof, and sound proof structure.
Heating and Cooling costs for homes built with ICFs are quite low. On an average the cooling and heating equip. can be downsized by 1/2. The operating R-Value of these homes can be between 30-40. Less dust, low noise admitance, and sound Building make this my choice for home construction. Because these homes are very tight,(infiltration) they need to install a HRV (heat recovery ventalator) to supply fresh air into te home.

Radiant Floor Heating

HYDRONIC Radiant Living has become one of today’s most sought after ways to heat your home. While it costs more initially to install, the notable savings will come when you compare fuel costs between forced air and radiant heating. Forced Air Systems generally use twice as much fuel as HYDRONIC Radiant Systems, due to convective currents. Convection transfers heat by the flow of a gas (air). A gas expands when you heat it, and decreases in density. In other words, it gets lighter. The lighter, warm, air will rise through the cooler, less dense, air creating convective currents. Thus, hotter air at the ceiling, cooler air at the floor. The hotter air at the ceiling wants to get to a cooler place, and that cooler place is the attic. The greater the temperature difference between the attic and the hot ceiling, the more heat loss to the attic. This results in higher heating bills, due to the greater heat loss. HYDRONIC Radiant heat is equal in temperature from floor to ceiling, resulting in less heat loss to the attic. If the floor is 70 degrees then the ceiling is around 68-70 degrees.

HYDRONIC Radiant Heat is the transmission of energy in the form of waves, an example of waves is sun light. Have you ever stood in front of a window on a sunny day and felt the suns rays warm your skin? This is Radiant Heat at its best! Energy, or waves travel at a different wavelengths. And that brings us down to the business about heat rising. Heat doesn’t actually rise you know? It moves through a solid object, or rides on a gas or liquid, or flies through space. Heat always goes to cold, because mother nature always wants to equalize everything. Hot air rises, not heat!!

That’s why HYDRONIC Radiant Heat is so comfortable, you’re not heating the air so you have no air currents. And no air currents means less body heat loss due to evaporation, resulting in more comfort. Radiant heat is more involved with heating up objects in a room, than heating up the air, unlike a forced AIR system. No more cold feet, while walking barefoot on tile, wood, carpet, or vinyl flooring.

Today’s HYDRONIC Radiant Systems are designed around comfort, energy savings, and ease of operation. Usually incorporating multiple zones, night setbacks, outdoor temperature resets, and indoor feedback (via the thermostats). Today’s systems may also incorporate boiler- heated domestic hot water ( potable water), towel warmers, spa tub heaters, and snow melt systems for driveways, sidewalks, and parking lots.

Zoning usually consists of putting bedrooms and bathrooms on separate zones from other parts of the house. This is to make sleeping quarters independent of main living quarters and provide better temperature control for the occupants.

The most common floor piping material used is Oxygen Barrier PEX pipe. PEX has shown excellent characteristics for floor heat applications, and has been around since the early 1970’s. Typical tube spacing on the floor is 6″ to 12″, and concrete is 1.5″ to 2″ above the pipe which is imbedded in the slab. Or a staple-up method can be used in floor joists where piping is looped through the floor joists. The floor joists are insulated with foil-backed insulation which directs the radiant heat to the floor. Also, GYP-CRETE can be poured on 2 and 3 story buildings as an alternative to staple-up methods, and is far more superior because of its thermal mass and lightweight properties.
