Heating and Cooling

Wilder Plumbing & Heating has the capability to design and install the best possible heating and cooling system for your needs no matter what your budget. We consider ourselves a progressive company that stays up to date on the latest technology in the heating and cooling industries. We are committed to designing and installing systems that use the most energy efficient and environmentally friendly equipment and materials available.

Radiant Heating

There is simply no heating system more comfortable than a radiant panel heating system. Warm water is circulated through cross-linked polyethylene tubing which is installed in either a concrete slab, under your floor, or in your wall or ceiling. Radiant heating can be installed in new construction and in most cases can be retrofit into existing homes. Your floor becomes a giant "low temperature" radiator which heats not only your floor but all of the objects that are in contact with the floor.

A radiant systems is more efficient due to the lower water temperature required to operate it. There are no restrictions on furniture placement as with other systems because there are no floor registers or ugly metal baseboard panels. It is perfect for rooms with high ceilings as the warmth stays down where it is needed.

We installed our first radiant panel heating system in 1990 and have never looked back. There is nothing like the feel of a warm floor early on a cold morning.

And it doesn't stop indoors. Radiant snow melting can be used to keep walkways and driveways free of ice and snow.

Oil and Gas Fired Boilers

Installing high efficiency oil or gas heating equipment is the starting point when it comes to installing a heating system. Your boiler is the "heart" of your heating system. By using only the highest quality, most efficient equipment you can be sure that you will be getting the most value for your heating dollar.

Upgrading your old oil or gas boiler to a new high efficiency unit with today's energy saving control systems can usually pay for itself in only a few years.

We recommend and install high efficient and environmentally friendly heating equipment because it offers the best available technology and quality in the industry.

Geothermal Heating & Cooling Systems

Your own backyard has the potential to be an energy source for heating and cooling comfort. Outdoor air temperatures fluctuate throughout the year with the changing seasons. In contrast, ground temperatures about four to six feet below the Earth's surface remain relatively moderate and constant all year. That's because the Earth absorbs 47% of all the heat energy that reaches its surface from the sun. A geothermal system circulates a water-based solution through a buried loop system to take advantage of these constant temperatures. A single piece of equipment has the ability to heat and cool your home, while providing some or all of your home's hot water as well. Geothermal systems can save you 30% to 70% on your monthly utility bills, use no fossil fuels and are totally emission free.

High Velocity Heating and Cooling

Small Duct- High Velocity Heating and Cooling Systems deliver superior comfort over traditional HVAC systems by eliminating drafts and removing 30% more relative humidity. They outperform conventional heating and cooling systems by utilizing a high velocity stream of air. This air is delivered quietly into the room using small 2" outlets or an 8" x ¾" slotted diffuser instead of the large supply registers of conventional "air systems". These systems are not only a great choice for new construction; they can be installed in an existing home with very little esthetic impact.

High Efficiency Control Systems

We can install controls on your new system that will offer the latest technology for both fuel savings and comfort. We can also upgrade the controls on most existing systems to make the most of your fuel dollar and keep you more comfortable. There are many control options that are proven money savers. We can install thermostats that communicate with each other or weather responsive control systems that adjust your heating systems water temperature according to the outdoor temperature.

Would you like to operate your heating and cooling system controls from your computer anywhere in the world? We can do that too!

Solar Hot Water Systems

The sun provides readily available energy and Wilder Plumbing & Heating can help you take advantage of it. We design and install solar systems for heating domestic hot water as well as heating your home.

Do you have a swimming pool? There is no better way to heat your pool than by using "free energy" from the sun.

Indoor Air Quality

Today's more efficient and more air tight construction methods have created the need for the use of Heat Recovery Ventilators or H.R.V.'s. Today's well insulated homes can be great for our energy bill but are not always good for our health. These units provide fresh air to your home while exhausting stale air to the outside. The heat from the warm stale air is captured and used to pre-heat the incoming fresh air for greater energy efficiency.

We use and highly recommend the following products. These manufacturers are proven to be the leaders in the industry for quality, efficiency and innovation:

Weather, Windows, Walls & Warmth -- How Much Heat Do I Really Need?

Rising fuel costs are driving today's heating system technology to higher standards of efficiency.

Europeans have been dealing with much higher fuel prices than Americans have for years so it only makes sense to follow their lead when it comes to heating system technology.

As our fuel costs increase so does the need for systems that cost less to operate. The days of the, "bigger is better" systems are becoming a thing of the past and that's a good thing for the consumer.

Let's take a look at the old method of sizing a heating system.

Take the coldest day of the year that you or your grandfather can ever remember experiencing. Now since he said it was -30 for one solid week back in '34 we better play it safe and figure our outdoor design temperature at -40 "just to be safe".
Measure up all of our outside walls, glass, doors etc. do some math, and come up with a heat loss calculation, which by the way, already had a little "fudge factor" built in.
Now we all know that that's what we came up with on paper but "just in case" maybe we should add a little more after all they'll never complain about "too much heat". So let's add a "little more", "just to be safe".
Consult the boiler manufacturer's literature and find two choices, one slightly below our calculation "with fudge and safety factors" and one quite a bit above our calculation. So of course, we'll choose the larger one just to be safe because, again, "they will never complain about too much heat"!

Heating systems of the past were always designed for water temperatures of 180 to 200 degrees, sometimes even higher. Enough radiation was then installed to maintain 72 plus degrees, at again, an exaggerated design temperature. Now let's think about this; first your grandfather was wrong when he told you it was -30 for one solid week in 1934 (in fact, this chart will give you a better idea of realistic temperatures in Concord NH).

Now realize these are averages and indeed we do get below zero weather but for very few hours per year. So this means that there are very few hours per year we need 180 degree water to heat our homes.

Weather responsive control systems or "outdoor re-set controls"

As discussed above, a heating system is sized for the coldest day of the year. If a system is designed to heat your home to 70 degrees at an outdoor temperature of -20 degrees that means that you need your system to heat water to the system design temperature, (usually 180 - 200 degrees) when it is -20 outside. But in reality how many hours a year is it actually -20 degrees or whatever is your outdoor design "worst case" temperature. In reality it's very few hours per year. An outdoor re-set control adjusts your systems water temperature according to the outdoor temperature.

The key to saving is in the 3 - 1 rule. For every 3 degrees you lower your heating water temperature you save 1%. This can be substantial. Now indeed you will need that 180 temperature for those few hours a year but let's say its 45 degrees outside not -20. Now we can adjust our heating water temperature down to 120 degrees instead of 180 degrees. That is a 60 degree drop in temperature. So if for every 3 degrees we lower our water temperature we save 1% and we dropped the temperature 60 degrees. We just saved 20%.

Weather responsive systems are the least expensive way to save serious money on your heating fuel costs. They can be used on almost any hot water system and are not difficult to install and program.

These systems create a high level of comfort as they maintain a more constant, steady temperature. It is like a car driving on the highway at a steady 65 mph versus city driving from stop light to stop light and accelerating in between.

At Wilder Plumbing & Heating our specialty is designing and installing these high efficiency hydronic systems and doing it using the best available products and methods. We can also incorporate these methods into most existing systems and incorporate them into almost everyone's system improvement budget.
