Despite building a new home with the latest and best materials , the house will not necessarily be cost-effective , which requires a small financial outlay at the time of use (heating, electrical energy and heating water , repairs , maintenance of the house and keep desired temperature and humidity levels) .

In certain geographic areas , especially away from the cities there are usually no choice of heating energy source . In addition, the same house, depending on the location will need different amounts of energy (up to several hundred percent) .
This comes from the fact, that heat loss depends on many variables, which are based on the climate, location , weather conditions:

• sunshine heating of the house
• masked from the wind
• time of day and year
• location of the building relative to geographical directions
• humidity
• the size and placement of window panes and their thermal parameters
• architectural design

In addition, architects are continuing to make projects , that are far from cost effective, both during construction and living .
The more different from the cube shape, the more funding for heating will be required. The roof structure and the shape is even more important , through the roof has most heat escapes .
This is due to the increase of the external surface of the building in relation to the same volume inside, which increases the energy losses and escapes through the walls and roof.
In addition, little problems with the heat insulation and the correct implementation of the slopes , mergers , angles , which usually constitute ” thermal bridges ” .
In the case of  the same building –  differences in energy costs depending on the source of energy may be as high as 500% .
Thus,  it is necessary to use low-cost and renewable energy sources and the implementation of automation control of boiler room and all its elements .

You sould also realize which also affect house budget,  long-term (eg 10 – 20years) expenses related to:

• heating,
• ventilation,
• home renovations,
• repairs needed as a result of misuse home , etc .

For example, it is possible to reduce expenditure on heating energy in winter by a complete blockage of air exchange and ventilation (proof house), but on long term it will have:

• No escape of water vapor and humidity inside the building
• the necessity of frequent repairs due to the increase in humidity
• the possibility of fungal , mildew difficult to get rid
• appearance nusty smell
• can cause a variety of allergic disorders , asthma , malaise , depression, feeling constantly tired
• dampness of the walls and the deterioration of thermal performance of building materials
• moisture in the rockwool roof heat insulation and it will Fungal and drastic deterioration of insulation factors , because water conducts heat 25 times better than air
• dampness and deterioration of the roof rafter in pathological cases can cause neccessary to replace it
• that reasons can force  a drastic overhaul of entire attic insulation which entails internal slopes and ceilings as well

Taking into account the natural moisture resulting in a new home during construction, resulting from the wet processes, it is necessary to ensure efficient and unconditional ventilation, even despite the imaginary increase expences on house heating.
Proof windows, too fast construction process , Styrofoam insulation put when building is not sufficiently dry, cause that the building creates a thermos or greenhouse, and there is considerable opportunity to increase moisture and mold building. This may result in the necessity of renovation and repairs after first winter in new house.

Energy savings should therefore be given in moderation, ensuring all possible ways to keep your house in “good condition” for the longest period of time.

Application of optimum heating and recuperation (heat recovery ventilation) allows you:

• to dry up the house
• remove of water vapor
• small heat loss and proper air exchange maintain house at the correct temperature and humidity

Automatic ventilation , central heating system apparently , not only increase the cost of installation. It is also the most important element in the control house, causing the greatest gains, comfort, convenience and healthy living in the building for many years .

Thus, Boiler Room controller is the heart of  home automation and directly controls all the systems maintaining the house in good condition and make it more economical.
To comprehensively and safely control the central heating, HeatManager controller was dedicated and integrated in eHouse system , which is optimized for maximum energy savings , high functionality and comfort, ensuring appropriate conditions for use of the building, unattended operation for a very well-equipped boiler .
The devices controlled by HVAC, Central Heating & Ventilation Controller – HeatManager :

• fireplace with water jacket and hot air distribution
• recuperator
• fans to support the work of recuperator , ventilation, air circulation at the fireplace, etc.
• boiler or heat pump
• solar panels
• hot water buffer
• Ground heat exchanger
• water coolers
• water heaters
• bypass in the system of ventilation and recuperation
• three-way valve (cuttoff) to regulate the temperature of the water radiator , water heater in circulation recuperator or underfloor heating

HeatManager – heating controller has dedicated outputs for relays to integrate elements of heating and recuperation elements in one installation and alarm outputs to ensure the safe operation of whole system.

Key features and capabilities of the HeatManager controller:

• Control the boiler On / Off , blocking fuel supply , Power Off , manual injection

  • Manual –  settings (level of ventilation , heating , cooling) are taken from the current work program HeatManager.
    After reaching desired room temperature ventilation is turned off .
  • Full Auto – ventilation level is set on the basis of the current HM work program .
    The rest of the ventilation parameters are selected to achieve the required level of temperature in the room at the lowest cost energy for heating or cooling .
    After reaching the required temperature ventilation stops .
  • Unconditional ventilation – ventilation level is selected on the basis of the current work program.
    The rest of the ventilation parameters are selected so as to achieve the required degree of temperature in the room at the lowest cost energy heating or cooling .
    After reaching the required temperature ventilation is still working, adaptively changing the temperature,  to keep the room temperature at the programmed level.
• Actuator Control Bypass exchanger in the recuperator .
• Adaptive control of electric three-way valve , supply water temperature control water heater (to heat the air blown into the rooms) , radiators or underfloor heating .

• Indication of the level of heating in the fireplace .
• 3 built-in PWM dimmers , along with drivers thay may allow a smooth variable speed of DC fans.
• Overheating, fire alarms , Boiler , solar system.
• Switch actuator inlet probe / GWC .
• It has 24 built-in work programs including all parameters and settings of HeatManager.
• Built-in advanced calendar – scheduler, 248 items to run the system event .
• It has a built-in communications, self test , watch dog timer , protection against halting or hang-up. The device is reset in the absence of communication .
• It has fimware upgrade features  with eHouse PC software for increasing its functionality or release of new firmware , without direct access to the controller – directly from the PC application.

Manage by programs is the main way to control HeatManager. 24 work programs are defined (program integrates all the parameters (temperatures) measured at certain points of hydraulic – ventilation installation and if temperature thresholds are exceeded in one or the other direction device associated with the temperature sensor is switch on or off. To free user from remembering and manually run programs, HeatManager has an advanced calendar – scheduler , which can automatically change between heating programs or run other HeatManager events depending on time of day , Month , hours, etc. .

Important installation instructions:

• The air supplied for combustion in the fireplace and the boiler shall be provided outside the building for usage cold air for burning proccess not warm from the house .
• The use of turbo – fireplaces (ventilated with fans) is a mistake because in the case of obstruction of the chimney , absence during the initial phase of smoking blow in fumes and smoke into the house.
• Fireplace must be operated by gravity (no forced airflow) and only a string is produced by a chimney, which should be broad enough and protected from above against precipitation , wind blow (reverse direction), etc. .
• Fireplace in order to generate the maximum amount of heat, for the home should be equipped with a damper , that very little heat will escape through the chimney .
• Air intakes should be installed in the direction of most frequent winds blows to increase string of recuperator.
• Air intake at the ground heat exchanger must be equipped with a well to collect water from condensation as a result of going through the dew point temperature change of air.
• Pipe ground heat exchangers have to be laid with a fall in the direction of the well.
• Condensate must be removed in order not blocking vent pipe by gattering water.
• Air intakes and ventilation ducts (each side) must be secured with wire mesh against insects and rodents.
• The use of ground heat exchanger requires the use of a fan to assist the work of a recuperator to compensate pressure loss on supply air.
• Water cooler can be installed before the ground heat exchanger or after. Type of installation depends on the temperature of the cooling medium. In the case of cooling / heating water from wells is recommended to install at the air intake .
• Air intake before the ground heat exchanger should have a funnel shape tapering towards the ventilation duct. This will increase flow over the GHE in the case of wind and the effect is achieved as air compressor.
• Supply air pressure must be greater than the pressure of the exhaust air. Too little pressure of air entering the recuperator in relation to the outgoing lead intake air from outside through the holes , leakage , Flues ,chimenys etc .
• The process of recuperation requires condensate to the vessel in some types of recuperators (when temperature difference exceeds the dew point) .
• Temperature measurement of fireplace convection is made about 1cm from the chimney pipe and must be firmly fastened. Touching the sensor to the chimney will cause damage because they can operate to 110C and the temperature of the chimney can reach 400C. If Sensor location is too far from chimney, it will result in earlier turn off control and later turning on the automatic control of heating stove (working only with high values). Proximity of sensor should be preferably chosen so that the maximum combustion temperature of the convection in the fireplace was between 90 – 100C .
• Temperature sensors must be inserted in the mantle test points as deep as possible and push the wall, to get the lowest inertia measurement. Alternatively, you can stick them to a vertical copper tube as close to the fireplace (above fireplace).
• In the event of a recuperator and installation of the fireplace instead of the HAD, it is better to use a fan that forces air flow around the burning chamber ( low power (12V / 1 – 5W) as in PC power supplies) . The nearest exchoust to recuperator (located near the ceiling) will automatically take the hot air and warm-up the cold fresh air from outside .
• Channel bonding HAD fire and ventilation recuperator is a mistake . Recuperator will suck in dirty air above the burning chamber.
