Sanierung der Heizung in einem Einfamilienhaus

Dear Ms. Wenzel, June 20th, 2010, will be the 10th anniversary of our business, while at the same time our village will be celebrating its 700th birthday. On that day, we will host an in-house exhibition on our premises. We would like to present your products, PowerTank and WKS. In addition, we would like to give expert lectures at fixed times on that day, and we would appreciate if you could find a speaker to give a lecture about your products. Annexed please find pictures of our initial PowerTank system. We have built this as a pilot plant. The result is more than satisfactory: the system has demonstrably saved 50 % of fuel oil. With this experience we would like to generate more PowerTank orders. We would be pleased to receive your feedback soon. With kind regards from Unzenberg Thomas MĂźller S1

Step for step to success! A Customer Report

Existing System HT boiler with forced-air gas burner (22 kW) with integrated hot water pump, 160 l storage Heat exchanger for under-floor heating with integrated pump Temperature limitation in the LT section (max. 50 °C)

Expansion Phase 1 in 04/2006 Production of hot water using solar energy, no direct heating of the tap water Heating by increasing the outlet flow temperature in the LT section. No use of the existing components from the old heating system (replacement option for renewal) Use of paraffin instead of water as a storage medium, acts as a continuous-flow heater for tap water, no buffer tank for tap water Temperature control by room temperature instead of outside sensor Reduction of burner output to the new paraffin storage medium. Heat absorption into paraffin occurs more slowly than with water as storage medium. This feature is advantageous in solar operations. When the burner is throttled, it can run for a longer time to meet the energy demand as required. Gas consumption per time is lower than under full load. The required heating energy is the same, regardless of the running time of the burner. There are fewer «cold starts» than with the burners running near their capacity limit, resulting in a reduction of overall consumption. Phase 1: Burner output is throttled from 22 kW to 17 kW, reducing the exhaust temperature from 188 °C to 140 °C. The average burner run-time after this reduction was app.23 min. Phase 2: The burner is throttled from 17 kW to 11 kW, resulting in an exhaust gas temperature of 120 °C. The average burner running time was increased to 68 min, leading to an average of only 10 starts per day in February 2009. Here the running time of the burner amounted to about 85 % of the system’s heat demand time. Cycle losses were thus reduced, and the boiler operates at maximum efficiency. This further reduction of burner output should also provide

Heat support with solar energy for a paddling pool with PowerTank Energy Silo

After successful employment of the PowerTank latent storage system for the drinking water supply in the Neckarsulm lido, in a 2nd project solar powering of the children’s paddling pool was implemented.

Project goal: Heat supply using the PowerTank latent storage system and 40 m² of KBB solar collectors to protect against nocturnal cooling, swimming pool exclusively solar-powered, surplus is stored in the PowerTank Energy Silo. Thus the swimming pool is kept at 20–25 °C overnight. Projected break-even according to the city of Neckarsulm: 3 years Data Energy Silo: PowerTank latent energy storage system Energy Silo multifunctionally installable/integratable, consisting of: 30 pcs. WZ-1800-1WT 1 pc. concrete hopper, 2500 mm nominal bore Height: 3500 mm Nominal bore: 2000 mm Interior insulation PSE 250 mm Completely installed and piped ready for connecting and sub-surface installation Usable heat quantity: c. 360 kWh Cooling losses: about 1–2 °C per night Commissioning: May 2010

Installer: Halter GmbH, Neckarsulm

Versorgung des Kinder-Planschbeckens mit Sonnenenergie und PowerTank Energy Silo

Customer Report Basis: Traditionally, the children’s pool has not had a heating of its own. After replacing the filter system, the residence time of the basin water could be considerably prolonged without incurring hygiene problems. Because of cooling out (overnight and on suboptimal swimming days), the basin volume of 90 m³ must be drained very frequently and be re-filled with heated water from the clean water pipe of the swimmers’ pool. In the self-contained equipment room of the paddling pool, no fossil fuels are available. Installation of a basin water heater is precluded by spatial restrictions. Solution: The use of a paraffin-based latent heat storage system offers the advantage that solar energy can be saved significantly better than with water-based storage. The cooling of the basin can be compensated with this stored heat energy as required. Payback calculation: Cooling would necessitate emptying the pool 2.8× per week on average. Therefore during one swimming season of 20 weeks some 5,000 m³ of heated water are required. The price of water can be calculated at 5.50 EUR per m³ (including heating and disinfectant). This results in a total of c. 27,700 € per swimming season. If the necessary emptying after load factor according to DIN 19643 for the treatment of swimming pool water, namely 1× per week for a solar-heated pool, is used as a basis, for 20 weeks of bathing there will result operating costs of 8,100 € (taking into account the energy costs from the solar power generation for the heating of 1 m³ of water). Consequently, per swimming season 19,600 € will be saved.
