Benefits of DSH

There are a number of features and benefits that occur from DSH Solar Underfloor Heating. The fact that huge out-of-pocket savings will occur, cannot be emphasized enough, however; there are many more things that contribute to the whole beneficial DSH environment.

Space & Economics

No huge ongoing and ever increasing expenses for energy in heating for as long as you live in the home and the system operates normally. Every square meter of your home can be fully utilized, and no room for ducts or radiators are required.

Cost of imported energy will inevitably and inexorably rise over the next few years. Based on existing 6% price increase trends, the price of energy will roughly double every 10 years due to compounding increases. The DSH system locks in those savings for the life of the home.

Green/Eco Friendly

Virtually Zero carbon emissions during the heating operation of this system. As this reduces the need for expensive oil imports, it becomes very close to carbon neutral. In some locations you may be able to sell your carbon credits to establish a secondary income stream, check with your local government.

If a PV (Photovoltaic) power station were added, the DSH system would easily become carbon neutral, and if increased substantially, the whole house could be designed to be energy carbon negative. For every home or business on the DSH system, less energy is consumed, less carbon emitted, and less cost to the owner.

100% offset of GHG carbon emissions for the life of the home or building. As this can reduce the need for external expensive oil imports, it becomes better than carbon neutral when transport and other factors are included..

For every kW of energy provided, 100% of this is carbon offset, resulting in serious GHG reductions. Some like to say the like to..

Hygiene & Health

There are huge positive health implications, especially for warmer countries where winter will typically not drop below freezing. For example: No dust is generated or circulated. The heating will help asthma sufferers as it reduces dust mites at floor level and can virtually eliminate toxic mould and mildew.

    Reminder: The World Health Organization (WHO) advises that you keep a home above 18.0c, because at this temperature mold and mildew is unlikely to grow heated normal living areas in your home.

No mold, no invisible allergenic spores, & warm home = improved health. In addition, forced air systems circulate all manner of things such as dust, bacteria, odours and more, while a hydronic heat is quiet and typically non-intrusive.

In a recent city-wide trial in Christchurch NZ where hundreds of homes were set up to ensure they maintained or exceeded world health standards, the level of sicknesses reduced to a point where significant savings in health-care were shown.

Comfort & Intrinsic Happiness

It is pure luxury in winter to come home to a warm home, not worrying whether you can afford to heat it. The DSH provides comfortable background warmth levels. During the design process, care is given to concentrating primary heat in places such as bathrooms where a warm floor on bare feet can be pure luxury.

Cost effective & Savings

Once installed, the DSH will typically provide a heating energy saving, from 50% to 100% over your typical heating costs, depending upon location. The improvement when compared to standard, poorly insulated existing home can be significant. Actual results will vary and can be optimized.

Once installed, the DSH will typically provide a heating energy saving, from 50% to 100% over typical heating costs. The improvement when compared to bog-standard, poorly insulated existing  homes can be in the hundreds of percent. Actual results will vary and can be optimized.

While every system varies, it is anticipated it will cost less than $45/Yr in electrical power to operate, almost zero for systems with attached PV.

Super Quiet

Compared to forced air or radiator systems, there is no noise, no annoying air noises or ticking as pipes or ducting  expand in floor voids. The system runs almost silently. In addition as their are no annoying drafts, dust etc is not circulated, a must for the allergy prone.

The DSH residential pump is typically a three speed 45-95w pump that is virtually silent when running and costs pennies a month to operate.

Residential 2nd Floor:

The DSH system is designed to operate with a specific ratio between heated floor area and Core size. A 2nd floor will require additional design work and may involve an increase in size of the heat core to achieve the best results. Higher than 2+1 floors is not recommended for residential deployments, but is possible. The DSH is optimally designed to heat one floor which is the equivalent of the SqM (or SqFt) of the heat-store area.

Remember the heat core is matched to the house footprint size, location, and circumstances of your build, meaning that the storage may not match the living areas on a 1:1 basis.

There is a limit to how much can be stored and recovered efficiently. Adding more solar panels must be a carefully considered solution.

Backup Heat

See the Options Page: Integrated Wetback or other boiler heat source is simple, and only requires a few extra components as long as the pipes are in place. The DSH system option with a Hot Water Heat pump integrated onto the system, will also provide backup hot water to the the domestic hot water system.

Note: A heat pump should be sized according to heat loss not just as per house SqM or SqFt: thus the actual size/cost of a heat pump is much lower in a thermally efficient home.

Optional Integrated Wetback (Wood fired boiler) or other boiler heat source is simple, and only requires a few extra components as long as the pipes are in place. We recommend a minimum boiler heat rating of 10kW for the wetback/boiler.

These options must be considered at the time of ordering, as the pump station changes significantly with each option.

A demand or standard boiler can supply required backup heating in colder areas.

Ease of control

DSH systems are fully automated for day to day running. Set and forget with periodical checks to ensure all is well.

Safety

The DSH uses some household power at very low power settings, typically less than a typical  incandescent light bulb when operating, and it only operates as required.

There are no risks as associated with flame heat, in gas or wood fires.

Power Failure

The DSH system includes a 30 minute UPS power backup system. This would account for more than  95% of all power outages.  Some power outages can be longer.

New DSH systems with drainback capability will have little effect other than the building will begin to cool as no pumps will function once the UPS depletes after ~30mins. By mid 2015, new systems will be equipped with drain-back pump stations making power failures mostly immaterial. It should be noted that the solar panels normally have fluid running through them absorbing the heat energy, and regular no flow during high periods of solar insolation can decrease their life expectancy

Larger batteries can be also installed where power outages are expected. The UPS will slow charge these.   A standard 850CCA deep cycle 12v battery may add 8 or more hours to operation of the system during power outages.

A backup photo-voltaic system can be purchased anytime that will run the DSH system for as long  as the sun is shining meaning the system is solar protected but will not function at night. If a PV system is anticipated during construction, the DC leads to >250w of PV solar can be routed to the UPS during power outages. During power outages, PV systems that are grid tied, typically shut themselves down as a safety measure, however the panels themselves continue to provide DC power that can used at these times to operate the DSH system. This is less costly to install at time of main installation

Other benefits of the DSH system:

Every square meter of living space in your home can be fully utilized as the system requires no ducts, floor vents, or radiators.

Can be integrated into passive and net-zero homes.
