Many of your questions can be answered by reading our Frequently Asked Questions.
A. Position the dehumidifier centrally in a home either in a hallway or perhaps on the landing. If you have a problem area then move the dehumidifier to that area.
Q. Is it easy to move around?
A. Generally yes as long as you are fit and able as all dehumidifiers have either a carrying handle (please refer to the particular model for weight and dimensions). Also castors are available for the Ebac 2000 & 6000 series of Dehumidifiers. Daitsu Dehumidifiers have rear recessed rollers.
Q. Do I need to use it in summer?
Q The specifications indicate that a dehumidifier can extract 20 litres per day yet the water container only hold 4 litres?
A. Maximum extraction rates are based on temperatures of either 32 deg C & 90% RH or 30 deg C & 80% RH. In the real world conditions within the
it reasonable to expect a maximum of around 4 or 5 litres per day as the extract rates decrease with a drop in temperature. UK
Q. I bought a dehumidifier and it runs all the time - why?
A. The dehumidifier that you purchased is probably not capable of removing the amount of moisture in this area. If your area needs to have 50 pints of moisture removed from it daily and you have a 40-pint unit, you will never catch up and the machine will run continuously.
A. Yes, but this can be either good or bad. The warmer the room, the easier and more efficiently you can remove moisture so the machine will have to work less. Depending on the size of the room, you could raise the temperature by 5– 10 degrees particularly if you use a desiccant dehumidifier.
A. That depends on the brand and model that you buy. Most dehumidifiers with manual humidistat controls will turn themselves back on. With the electronic controls, it varies. The Ebac, Mitsubishi, DD322FW "Simple, DD122FW MK3 and XDry units will turn back on and will continue to remove moisture at the humidity level for which you had set the machine. The Daitsu, & Ruby Dry dehumidifiers will not turn back on and need to have the "on" button pushed to restart, and while it is a quiet and excellent machine, it would not be a good choice for a second home or if you plan to be away from your house for extended periods.
A. That depends on the total square footage of all the rooms, the configuration of the rooms, and the openness between the rooms. The more open the rooms are to each other (not 3’ doorways), the easier it is. Having ceiling fans in the rooms to move the air would certainly help. If you don’t have ceiling fans you can add small, inexpensive fans in the rooms to help move the air in these satellite rooms into the main area where you have placed the dehumidifier.
A. All machines have an air filter mainly to protect the machine. However, the Mitsubishi MJ-E16VX has a far superior filtration system that includes a Photocatalytic filter. If you specially want clean air then please look at the Daikin MC707B Air Purifier
the (dBA) the higher the sound level. Remember, an increase in 6(dBA) is a doubling of sound
A. You should replace the air filters on Ebac machines every few months. Some general-purpose filters can be Vacuum or even washed out. Daitsu & Mitsubishi filters can be brushed or washed. The Mitsubishi Photocatalytic filter can be washed a number of times but should be changed every 2 years. The filters on the Ruby Dry including the Carbon Filter require checking & cleaning every two weeks and should be changed at least once per year. Do not allow an air filter to become blocked on any dehumidifier otherwise premature failure can occur.
A. Yes, permanent drain kits are available for the Ebac range. The XDry/DD322 range require a ½” i.d. hose. Mitsubishi, Daitsu & Ruby Dry require a 15mm i.d. hose.
A. The hose connects to a drain point on the dehumidifier and the hose outlet must be lower than the dehumidifier drain point.
A. The water would then go back into the integral tank and once full will switch off the dehumidifier.
A. We do not offer a wall mounted domestic dehumidifier. However we do offer a range of Commercial wall mounted dehumidifiers.
A. Only the Mitsubishi MJ-E16VX has a digital readout. Purchasing a Thermo-hygrometer is recommended so you can measure relative humidity and compare it with the setting on your dehumidifier. Do not expect the humidistat accuracy on the Dehumidifier to be as accurate as a thermo-hygrometer.
A. Either you have the setting on the dehumidifier too high or the dehumidifier is under sized. While a relative humidity level of 50% may be ideal for your home, you may have to lower the level in periods of colder weather and make your dehumidifier work harder.
A. This depends on the level of the problem. Generally, you will see an improvement within a few days but do allow 1- 2 weeks to get the problem under control.
, condensation in houses is mainly a winter problem particularly where warm moist air is generated in living areas and then penetrates to the colder parts of the building. Britain
The moisture in the air comes from a number of sources within the house. Water vapour is produced in relatively large quantities from normal day to day activities - a 5 person household puts about 10 kg of water into the air every day (without taking into account any heating) - i.e.
- breathing (asleep) 0.3 kg
- breathing (awake) 0.85 kg
- cooking 3 kg
- personal washing 1.0 kg
- washing and drying clothes 5.5 kg
- heating - especially paraffin and flue-less gas heaters. For every litre of paraffin burnt over one litre of moisture vaporizes into air. Every carbon fuel produces some amount of water from combustion.
* (1 kg of water equates to about 1 litre)
Moisture can also be drawn from the structure of the building into the internal air; from below the floor or through the walls/ceilings.
A. Yes, a dehumidifier will help prevent further problems but you must use a mould spore remover to actually kill the spores.
A. Traditionally dehumidifiers worked on the refrigeration principle where air passed over a cold refrigerated coil and moisture condensed on the coil and drained into a container. The compressor-less adsorbent machines such as Ruby Dry & XDry work on the principle of moist air being drawn into an absorber that is a slowly rotating disc impregnated with silica. A heating element applies heat to the adsorber that heats the moisture to a high temperature vapour that immediately condenses into water.
A. No, there is nothing to replace
A. Yes and no. What is most important is the amount of water you need to take out of the air. The more water in the air, the larger the capacity you will need. A small room with a lot of moisture may need as much dehumidification as a large room with average moisture content. When in doubt, it's always better to oversize a dehumidifier.
A. Yes you can. Ideally place your clothes on a drying rack and place the dehumidifier in the same room and leave on a continuous or Laundry setting. Shut the door to that area and the dehumidifier will take in all moisture. The Mitsubishi, Daitsu, and XDry all have a Laundry setting. The Ruby Dry is also excellent for this purpose. These machines have a high airflow to assist with the drying.
A. Normally one will be sufficient but in the case of very large houses or where you may have several floor then more than one may be required
A. Garages are generally unheated so consider the Adsorption dehumidifier such as the XDry or DD322FW "Simple" or Ruby Dry as these operate in low temperatures without losing extraction capacity. Larger Garages may need more than one machine.
Very large car storage areas, warehouses etc should consider commercial dehumidifiers.
A. The warmer the air the easier it is to extract moisture. Using a Ruby Dry or XDry is ideal if the temperature is generally on the colder side as these machines maintain extraction rates regardless of internal temperature.
A. Yes you can but be aware that there will always be a sound from the machine when it is operating. Choose a quiet dehumidifier if it is to be used near bedrooms.
A. All dehumidifiers are fitted with a humidistat that controls the operation of the machine. When the humidity level is satisfied, the dehumidifier will switch off though some machines allows the circulation fan to continue.
A. Check the wattage of the dehumidifier specification. Currently 1000w of electricity will cost you around 12-15 pence per hour. Therefore a machine rated at 250w will cost you a quarter of a kW so allow around 3-4 pence per hour if running continuously though adsorption machines will have a higher cost. However, the adsorption machines such as Ruby Dry & XDry will do the job quicker at temperatures below 20 deg C and therefore overall costs may be less than with a conventional dehumidifier.
Once the house is brought under control the actual running costs will be reduced, as the dehumidifier will need to operate less.
A. Yes they have. The Ebac 2000 range has auto and manual control. The Ebac 6000 range is fully automatic. The Ruby Dry has a setting of 40/50/60 %RH. The XDry controls levels to around 40-45% or 55% depending on setting. The DD122FW "Simple" & the DD322FW "Simple" have a rotary variable humidistat. The Mitsubishi MJ-E16VX the VX model is adjustable from 50-70%. The Mitsubishi MJ-E16VX is extremely accurate to within 1% of the setpoint. Daitsu machines can be set to 50, 60 or 70 %
A. Between 40 and 60% so the ideal would be 50% but may need to be lower in very cold weather.
A. We supply a desktop digital thermo-hygrometer that displays current temperature and relative humidity.
A. The coils of refrigerated dehumidifiers will ice up but a sensor or timer will stop the compressor and allow the ice to melt. This is normal but severe icing up can be due to a shortage of refrigerant, insufficient airflow or a malfunction.
A. Yes, all domestic dehumidifiers have a container that ranges from 3.5 liters to 5.5 liters capacity.
A. Yes, all tanks are fitted with a float switch so once full they will shut off the compressor.
A. If you order prior to on any working day you will normally receive the machine the following working day. However, deliveries to the Highland & Islands or to
may take 2/3 days. Northern Ireland
A. We can arrange delivery on a Saturday for an additional cost of £25
A. No, as long as you have a safe place where it can left and give us your permission along with leaving a note with your signature for the delivery company. We can also arrange delivery to your workplace if that is more convenient to you.
