About Pool dehumidifier

4. Where need the dehumidifier?
Dehumidifiers are often placed in the following areas where excess moisture is most prevalent:
Spas or Indoor Pool Areas
Crawl Spaces
Additionally, when you supplement your air conditioner with a dehumidifier, you will achieve the best balance of cool and dry air, which will help your indoors remain healthy and cool.

5. What exactly does a dehumidifier do?
A dehumidifier can help you remedy the moisture problem. These appliances are designed to pull damp, sticky air into the unit, rapidly cool it and condense the moisture, and redistribute the drier, dehumidified air back into your environment using a fan. The collected water drains through a hose and into an exterior receptacle (i.e., a floor drain) using simple gravity.

6. What is an ideal humidity level for my space?
For most spaces, it is ideal to maintain a 45~50 percent relative humidity level. Relative humidity levels above 50 percent create an environment where mold spores, dust mites, bacteria, and even cockroaches and other harmful pests thrive. Not mention an environment that fosters unpleasant odors and accelerated decaying and staining of surrounding structure and interior.

7. What about the operating costs of the dehumidifier; isn’t it expensive?
It may seem like it is, however the cost of repairing the structure from the damaging effects of excess moisture will far outweigh the dehumidifier operating costs over a long period of time. The operating costs of your dehumidification system will vary depending on;
The size of your pool
The size and design of your indoor pool room
Hours of use
Energy costs in your location
The costs of operation are more than recovered in terms of the comfort to users, the preservation of the investment and the overall long-term value of the facility. The costs of poor maintenance control can range from annoyance (condensation on windows) and reduced satisfaction (uncomfortable conditions on the pool deck) to catastrophic building damage (mold, mildew, rotting timbers, stained walls, insulation damage, window replacement, etc.).

8. What Size Dehumidifier Do I Need?
The size of the dehumidifier unit depends on the size of the area that needs humidity taken out of the air. The smaller the area, the smaller the unit that is needed. Too small a unit may have to run constantly to accommodate a larger space, so it is wise to make sure the unit you purchase is large enough to take care of the entire area.

About Pool heat pump 

4. Why choose a heat pump to heat my swimming pool & spa?
A heat pump allows you to heat your pool or spa economically. Depending on energy costs, an ALTO heat pump can save you up to 80% over propane gas, 50% to 70% over natural gas, and over 600% against electrical resistance heaters. This is the reason why thousands of customers choose a heat pump to heat their pool, rather than alternative types of heaters.

5. How does a heat pump heat the pool & spa water?
A heat pump simply moves heat from the air and transfers it to the pool & spa water. A heat pump uses a refrigeration cycle exactly like your refrigerator or air conditioner uses. A proven safe, economical and very trouble-free system.

6. How long will it take to heat the pool & spa?
The initial start-up heating time will differ, depending on the size of the pool, the air temperature at the time that you are trying to heat your pool. And some other considerations affect the time also, such as Pool location, Indoor or outdoor pool, surrounding water table level, windy exposed site or sheltered, desired pool operating temperature, required season to use the pool, whether the pool is covered when not in use and at night, whether it is equipped solar or thermal cover. However, once your pool reaches the target temperature you, the run time can be as little as only a few hours per day.

7. Is it difficult to install a heat pump?
Not at all, the heat pump needs a solid concrete base or can be laid on paving slabs. The unit then needs an electrical supply and it is best to get a qualified electrician to install this. And then you only need to finish the plumbing connection with your pool. Please note the heat pump should be installed after the filter and as the last item before the water returns to the pool.

8. Will it be damaged if my heat pump installed outdoors?
No, all of Alto heat pumps are designed to go outdoors and are weatherproof. They will operate perfectly well in all weather conditions including heavy rain and wind etc. We recommend that you cover your heat pump with one of our specially designed winter covers during winter when the heat pump is not in use. This will give your heat pump some additional protection against the weather.

9. Should I cover the heat pump in winter or stop using it for some time?
We recommend that you cover your heat pump during the winter. And we supply the suitable cover as the optional parts for your choice. Please not that the cover must allow the heat pump to breathe so that moisture and condensation can escape, otherwise corrosion can occur to the components in your heat pump causing permanent damage.

10. Can I use salt in my pool rather than chlorine, will this damage the heat pump?
Yes, you can do that. It will not damage the heat pump, because all of our pool heat pumps have titanium heat exchangers which are resistant to damage from salt, chlorine or bromine used in pools.

11. Are heat pumps safe and reliable?
Heat pumps are completely safe and a tried and tested technology. There are no hazardous gas emissions, no flammable oil, LPG or gas pipes, no unsightly fuel storage and no flues or chimneys with heat pump installations. There is no need for regular servicing or expensive annual safety checks, which can work well 10 to 15 years.
