It is important that new or replacement equipment is not sized by "Rule of Thumb" or by duplicating the existing equipment capacity. The only accurate way to determine the correct capacity of heating and air conditioning equipment for your home is to have a load calculation performed on your home. There is a specific method to do this calculation. This will give the heat gain and heat loss design data for your home.

The first step is to determine how much lumber you’ll dry in a year. Then figure your average drying time for each of the species you’ll be drying, and you can calculate the size kiln you need from there. For example: you need to dry 500,000 board feet of oak per year. Fresh off the saw, oak takes about 28-30 days to dry, so you’ll be able to do 12 loads in a year. Each load will need to be 42,000 board feet to give you the 500,000 board feet you need for the year.

American homes use approximately 10,200 kilowatt-hours (kWh) of electricity per year (about 850 kWh per month). Depending upon the average wind speed in the area, a wind turbine rated in the range of 1.5 to 5 kilowatts would be required to make a significant contribution to meet this demand.

It's a good question! Like all things, before we ask for anything, we ought to identify what we need first... To help expedite your need-identification process, please refer to the Facts to Consider section in Request Form.

For single-family homes, tanks typically range in size from 500 to 1500 gallons of wastewater storage capacity. For a one- or two-bedroom home, a 1000- or 1200-gallon tank is common; A typical 1000-gallon concrete tank measures about eight feet long by four feet wide and six feet deep. Check with your local building department for actual sizes needed.

Heating output is specified in kilowatts, kW, (metric units) or BTUs (Imperial units) and represents the rate at which the system can deliver heat energy. Sizing of heating systems should be done by a qualified heating engineer. It is dependent on many factors including levels of insulation and draught proofing of your home, lowest outside temperature of your locality and patterns of use.

The only way to determine what your actual requirement is to have a heat load done on your home by a qualified heating technician. This calculation looks at the size of the structure, insulation, doors and windows along with your climate area for outdoor design temperature. A heat loss is then calculated to determine what is required for the boiler and the heating elements to heat the structure.

In general, the size of electrical service ranges from 150 Amp to 200 Amp. We usually suggest 200 Amp service, especially in new homes. This also gives the homeowner some space for future additions. Installing a new electrical service is not a job for an unlicensed person to attempt. In most cases, it involves replacing everything from the service loop (the wire that extends from the top of your meter to the public utility tie in) up to and including the main electrical panel.

Every home is as individual as its owner. The key to selecting the right heat pump for your home is accurate estimation of the heat that will need to be transferred into your home in winter for heating, and out of your home in summer for cooling. This needs to be carried out by experienced and qualified specialists like Gavin Lowe Air Conditioning.

The general rule of thumb in aquarium keeping is to have no more that one inch of fish per gallon of water. Thus, if you had a twenty gallon tank (with no substrate or rocks to diminish the total water volume), you could have five 4-inch fish. This formula also assumes you will change 25% of the tank volume each week. See What is a water change? Why is it important? for more details. Realistically, however, you will need to consider the following factors when choosing what size tank to purchase:

Weight distributing is based on the amount of loaded tongue weight the trailer has. To purchase the correct size weight distributing hitch (WDH), you will need to first load the trailer as you would tow it down the road and then have the tongue weighed. You can weigh the trailer tongue by using a bathroom scale or taking it to your trailer dealer to have the tongue placed on a tongue scale.

While there is no such thing as "too much" power in a sound system, the system should be powerful enough to fill your room. To help you pick the right product, each HSU speaker and subwoofer has a "Loudness Level" index —a rule-of-thumb guide to point you towards the best system for your space.

Our measurements are given in stem thickness first followed by internal diameter/length eg.: 1.6 x 12mm. Our rings are always measured internally. Straight and curved barbells are always measured between the balls. On curved barbells (eg., belly bars) measure the shortest distance between the balls along the inside of the curve. Inches to millimeters conversion (you my need to round up or down to the nearest whole mm as necessary):

A ton is 12,000 BTU (British Thermal Units), a measure of how much energy the system outputs. There are many things which will determine the size system your home requires. Some of these are: square feet, number of windows, insulation factors, the direction your home faces, heat producing appliances and even the number of people who will be in the home. An energy analysis should be done on your home to insure the correct system. Limited warranty covers specific parts (i.e.
