Q. When can I use my Hot Tub?
  Every day of the year ! Each season is suitable for a relaxing soak in your Hot Tub. The soothing effect will be enhanced at colder outside temparatures because the muscles are more tense. After a half hour in your Hot Tub, you'll feel as new. And of course, the summer evenings are perfect for stargazing in our cedar hot tubs.
Q. How much does a Hot Tub cost ?
  Prices depend on several factors such as dimension required and optional accessories, installed or not, etc. Contact us for further information.
Q. What sort of maintenance is required?
  You need to monitor your chemical level each week. If the tub has been stained, this should be repeated annually to keep the rich color from fading caused by the elements. You might wish to let cedar age naturally to a "gray" color. You can do this by allowing the cedar to be exposed to the elements without any protection.
Q. What is the cost to operate my tub?
 

The circular construction along with the high insulating value of cedar and our Northern Elements Covers will provide excellent insulation value. Outside temperature and your local electric energy costs (cents/kwhr) are the main variables in cost. Some of our customers run their tubs year round in extreme northern climates (Alaska, USA -30° C) and in those conditions they are reporting a monthly cost of 35€/month.

Q. What is a safe temperature for my hot tub?
 

Typically most people feel that 37° C - 39° C or is a comfortable temperature, however, we recommend you contact your doctor to determine if a hot tub is safe for your given health condition.

Q. What are the differences between plastic tubs and your cedar tubs?
  Experience is the difference! Our tubs are 43" deep, providing a unique soaking effect that is not available in shallow plastic spas. The aromatic smell of cedar coupled with the relaxing soak, and therapeutic massage provides a unique experience that can’t be imitated.
Q. Is a wood tub hard to keep clean?
  Cedar is, in fact, naturally resilient to decay. It's rich oils give cedar the life span it is famous for. Cleaning is the same as with most plastic tubs. Typically, a light scrub brush with a diluted solution of liquid bleach works well.
Q. Is a wood tub less healthy then a plastic tub?
  In 1993 the Food Research Institute at the University of Wisconsin conducted tests to compare wood surfaces of cutting boards with the plastic equivalents. The assumption was wood would absorb the juices and become a hot-bed of disease. In other words, plastic would be safer. This wasn't the case. Seven species of wood and four types of plastic were tested. All were intentionally contaminated with E-Coli, Listeria and Salmonella. To everyone's surprise, the bacteria were killed within 3 minutes of touching the wood surface. This was not the case with the plastic surfaces.
Q. How powerful are your jets? Some companies advertise 80+ jets? How important is Horsepower when selecting a pump?
 

It is not so much horse power you are looking for. Our base 4 jet system comes standard with 2" discharge holes, and 1 1/2 HP power, with a true 1 1/2 HP impeller. On our 6 jet system the size is a true 2 HP with 2" discharge. What is more important is the flow per minute the pump produces which has nothing to do with horse power, rather impeller size.

Flow is the most important factor for jet operations. We use high flow jets made for wood hot tubs. A pump must be able to deliver the total flow that all the jets need and produce the necessary pressure to create that flow. We need more flow and more pressure as we go from 4 to 6 to 8 jets, and we do this by switching to different pumps with different (larger) impellers and different horsepower motors (1-1/2 , 2 and 3HP respectively). Once we get up to our maximum for 10 jets we still stay with a 3 HP pump but also slightly reduce the orifice size in the jets and increase piping size and fittings to 2" from 1-1/2" in order to ensure sufficient pressure remains for the jets and is not all lost in the piping. We also decrease the orifice size for 8 jet systems and switch to 2" piping if there is more than aft between the hot tub and the pump unit.

In today's spa market, companies are competing on the number of jets. A 2 HP pump powering 60 jets will not be anywhere near as powerful of a massage as the same pump powering 6 jets . The total flow rate of the 60 jets is the same as that of the 6 jets, meaning each jet has a much smaller orifice ( hole ) size . HP can also be a marketing gimmick . For example a 2 HP pump can be fitted with a 5 HP motor, but still not produce more than 2 HP. A properly matched pump that produces the flow required by the jet is what you are looking for. Jet companies rate their jets in gallons per minute of flow @ a specific psi of pressure. For example 13 GPM @12psi. If you have 4 jets each requiring 13 gallons per minute then your pump must be capable of delivering 52 gallons per minute and also produce sufficient pressure so that there is still 12 psi left for the jets after the pressure drop losses in the piping and components are factored in.

We design our tubs to be simple yet effective. The most jets we have is a 10 jet system with all high flow components including 3 suctions and a 3 HP motor. HP is not the same as flow therefore if you double your jets to say 8, and double the HP to 3, the pressure on the jets will not be the same . You need to do more such as widen the piping to 2" and include more suctions to have a similar effect.
