Inspecting Your New Home – Part 1

In the next three articles we will try to outline items a new home buyer should look for once they decided to purchase their dream house.  In this part we will focus on your home’s systems.

Heating
  • Check the furnace and hot water heater.
  • Ask about the capacity, shut-off mechanisms and the type of filtering systems installed.
  • Review the operation of your heating system.
  • Locate the furnace filters and ask about their care and maintenance.
  • Ensure that heat registers are not located below a thermostat.
  • Check the location and number of cold air returns and make sure they are unobstructed.
  • Learn the location of any fuel lines (gas, propane or oil) and understand how to operate any shut-off devices on these lines.
Mechanical Ventilation
  • Locate the switches for ventilation and circulation fans (normally placed near the thermostat).
  • Locate supplemental fans and switches in each bathroom and in the kitchen and ensure they are operating. Make sure you understand how to achieve proper ventilation in order to avoid condensation problems which may not be covered under the warranty.
Electrical System
  • Locate the main electrical panel and review the function of each circuit breaker and fuse.
  • Your new home must be equipped with ground fault and arc fault circuit interrupters (GFCI and AFCI). GFCIs protect bathroom and exterior receptacle circuits, while AFCIs protect bedroom receptacle circuits. Ask your builder how to test these devices.
Plumbing System
  • Locate the shut-off valves for the main water supply and the location of other shut-off valves throughout your home. It is your responsibility to shut off the water supply to all exterior hose bibs to protect them from freezing in winter weather.
  • If your home has a septic system, ask your builder to provide you with information on its use and maintenance.

Tank less hot water heater

With cost of utilities set to increase this year again, being efficient with energy use is always top of mind.   One of the ways you could save on your energy bills is by going the tank less hot water heater route.  Just to clarify, the traditional way to supply hot water is by using a tank type system, where the water (40 gallons and up) is heated in a reserve tank that is available anytime.  A tank less system on the other hand heats up water on demand (there are some hybrid models as well).

There are multiple factors to look at when deciding on this upgrade.  We will discuss the two crucial ones below:

  • Flow GPM(gallons per minute)

What is this? This is the amount of water that is being used.  To calculate how much water a fixture is using, take a measuring cup and measure how much water you have filled up in one minute.  This will translate in the desired GPM (Gallons per minute).  The following is typical usage per application:

Typical shower:  1.5 to 2.0 GPM
Typical bath faucet:  2.0 to 3.0 GPM
Bathroom vanity sink faucet:  0.5 to 1.5 GPM
Kitchen sink faucet;  1.0 to 2.2 GPM
Clothes washer:  1.5 to 3.0 GPM

For a comparison basis, a with a typical shower of 2.0 GPM, a 40 gallon tank from a tank type system will have water available for 20 minutes ( a very long shower). Given that most households have dishwashers, laundry, and multiple bathrooms, at least a 3.5 GPM or higher heater would be recommended.

  • Temperature Rise (TR)

What is this? This is the difference between the temperature of the water coming into the house (supplied by the city) and the temperature of the hot water required.

Why is this important? The flow rate of tank less water heater systems depend on temperature rise.  All manufacturers will supply this information.

For example (and the eyes are starting to glaze over) :  Given the desired temperature is 110 degrees Fahrenheit in a case where the water temperature from the city is 75 degrees, the temperature rise is 35 degrees.  Let’s say at this temperature rise a given tank less system delivers 7 GPM.  If the water temperature from the city is 35 degrees Fahrenheit, the temperature rise will be 75.  At this rise, the same system might only deliver 4 GPM.  This is a very important concept when choosing a system.

As with anything that will save money, the upfront costs are higher (why should the homeowner pocket the savings instead of the manufacturer).  But the fact remains, energy prices are going to increase over time and investing in an energy efficient system should reduce the operating cost of the home.
