Equipment Installation Examples

These pages provide installation examples of the many different types of equipment we install in businesses and homes on the Vineyard.

Air Separators – Air Elimination and Purging in Boilers

All hydronic (water based) heating systems use water to convey heat and there is always some air present in this water.  When the amount of air is too great, circulation in the hydronic system will stop, usually resulting in a no-heat service call.  This air can be continuously and automatically removed by an air separator. The air separator has a stainless steel…

Buderus Condensing Boiler – 96% efficient

The Buderus condensing boiler is simple to install, service, and operate.  We like its flexibility with flue piping as we can use 3″ PVC pipe with no clearance to combustible materials.  Here is an installation of a mid-sized (60,000 Btu/hr) GB142 model.  The flue piping is 3″ intake and exhaust PVC piping which exits the side of the building. Our goal is…

Controls – DDC (Direct Digital Control) Upgrade for Complete Remote Control

We often get asked to rebuild complicated control systems to modernize them and restore their correct function.  Many times, we see control panels that are chaotic and poorly laid out, incorrectly assembled, or just not working. This is the before picture of a control panel that was a mess so we carefully labeled all of the wires and then rebuilt it from the…

Controls – Emergency Override Panel Protects Against Power Surge Damage

Several years ago, a hurricane came fairly close to the Vineyard and several parts of the island lost power for a few days.  As the high winds were sweeping across the island, various power lines were intermittently shorting out which wreaked havoc on power going into the nearby homes. In this particular home, the emergency generator sensed the loss of power, turned…

Daikin Heat Pump – Flexibility and Efficiency

Here are some installation pictures of the now classic Daikin inverter heat pump.  This outside unit is their largest residential offering and is able to provide refrigerant to up to 8 inside units. Here is a series of three of these heat pumps which are able to heat and cool the entire 10,000 square foot house       This inside unit…

ECM Smart Circulator – Bell Gossett EcoCirc Vario

Circulators are a vital part of any hydronic system.  They provide the pressure differential to make the hot (or chilled) water flow through all of the piping to all of the heat emitters in the heating system. Up until a few years ago, all circulators in the US were single speed and were either on or off.  This was fine until we…

ECM Smart Circulator – Bell Gossett EcoCirc XL

The larger versions of the ECM circulators have a tremendous amount of features.  While they are designed for the commercial market, we have found that they work well in our larger residential installations.   The Bell Gossett EcoCirc XL is their flagship ECM circulator. Here is an example of a twin circulator set up – the two pumps talk to each other…

ECM Smart Circulator – Grundfos Magna 3

In addition to the Bell Gossett EcoCirc XL, we also offer the Grundfos Magna 3, which is the flagship ECM circulator for Grundfos.  It too has a tremendous amount of features and was also originally designed for the commercial market.  We have had great success with Grundfos circulators in general and have found that the Magna in particular is very easy to…

Heat Pump Water Heater – more than 200% efficient

Heat pump water heaters use a small heat pump to extract heat from your basement air and use it to heat your domestic hot water.  They are easy to install (essentially the same as a regular electric water heater) but are much more efficient.  We offer the Bradford White version which is identical to the GE heat pump water heater.  Pictured above…

Outside Reset control installation

Outside reset control is an important part of making a hydronic heating system efficient and comfortable.  It is a control scheme that basically “resets” the temperature of the boiler water based on how cold or hot the outside temperature is.  The thought is that outside temperature will give us a direct idea of how much heat a building is losing and what…

Solar Circulator Failure and Replacement

All systems need maintenance to function at their peak efficiency and to work successfully for their entire service life.  An additional issue to consider is how often systems will be left inactive.  When mechanical systems are idle for long periods, seals can fail, valves and moving parts can get sticky, and fluids can start to change their composition. This particular circulator was…
